The Unattended Ground Sensor (UGS) are a variety of small sensors, generally covert, dedicated to detect and identify activities on the ground such as enemy soldiers or vehicles. UGS come as systems with an integrated communication network and processing capabilities.
The unattended ground sensor were under development as part of the United States Army's Future Combat Systems Program. For information on currently fielded UGS systems, refer to the Current Force UGS Program [1] or CF UGS.
The CF UGS systems employ various sensor modalities including seismic, acoustic, magnetic, and pyroelectric transducers, daylight imagers and passive infrared imagers to automatically detect the presence of persons or vehicles, and transmit activity reports or imagery via radio-frequency (RF) or satellite communications (SATCOM) links to a remote processing, exploitation, and dissemination (PED) station. The systems are packaged for concealed emplacement in the field and for long-duration unattended operation. [2]
The Army Research Laboratory developed unattended ground-sensor technologies for detection and tracking of personnel and vehicles for perimeter defense and border-monitoring applications. In 2005, the OmniSense system was commercialized and fielded. [3] [4]
The CF UGS program includes a family of sensors from various companies: Qual-Tron Inc (MIDS, EMIDS, MMIDS) E-UGS, Silent Watch, Falcon Watch, Scorpion, OmniSense and OmniSense-Enhanced. The current sources for CF UGS are Applied Research Associates (E-UGS), Harris Corporation (Silent Watch, Falcon Watch), Northrop Grumman-Xetron (Scorpion), McQ Inc (OmniSense, OmniSense-Enhanced). [1]
There are two types of unattended ground sensors that are being fielded under the United States Army's Future Combat Systems Program, the Urban UGS or U-UGS and the Tactical UGS or T-UGS. The current generation is manufactured by Textron Defense Systems a subcontractor under Boeing.
T-UGS are small ground-based sensors that collect intelligence through seismic, acoustic, radiological nuclear and electro-optic means. These sensors are networked devices that provide an early warning system to supplement a platoon size element and are capable of remote operation. To an extent T-UGS will detect, track, classify, and identify personnel and vehicles within its coverage area and report to the FCS Network in near real-time.
T-UGS comprises the following sensor systems:
For urban areas, the urban-unattended ground sensor (U-UGS) is used as a surveillance tool during building clearing operations, and in caves, sewers, tunnels, and other confined spaces. Textron Defense Systems, along with Honeywell, designed these wireless, hand emplaced system of sensors to be lightweight and low cost. The U-UGS network is capable of taking field-of-view images of intruders in all light conditions and transmits images to the FCS Network where immediate recognition of human intruders should be achieved, or, when imaging is not needed, by using the motion detector sensors only.
The proposed U-UGS sensors are made up of the following:
The Army Research Laboratory (ARL) developed Omnisense for perimeter defense and border-monitoring applications in collaboration with McQ Inc. In 2005, the OmniSense system was commercialized and fielded by the U.S. Army. [5]
Persistent surveillance sensors were deployed in quantity to war-fighting areas to monitor roads, borders, and areas of interest for insurgent activities. [6] This networked UGS system connected users to remotely deployed sensors, enabling the receipt of target information and allowing for the remote reconfiguration of sensors [7] The detected targets were tracked with either a daytime color camera or an uncooled nighttime infrared camera, so the user sees the target as it is detected. [6]
The US Army has cited OmniSense as “One of the Greatest Inventions of 2006.” [7]

Measurement and signature intelligence (MASINT) is a technical branch of intelligence gathering, which serves to detect, track, identify or describe the distinctive characteristics (signatures) of fixed or dynamic target sources. This often includes radar intelligence, acoustic intelligence, nuclear intelligence, and chemical and biological intelligence. MASINT is defined as scientific and technical intelligence derived from the analysis of data obtained from sensing instruments for the purpose of identifying any distinctive features associated with the source, emitter or sender, to facilitate the latter's measurement and identification.
Wireless sensor networks (WSNs) refer to networks of spatially dispersed and dedicated sensors that monitor and record the physical conditions of the environment and forward the collected data to a central location. WSNs can measure environmental conditions such as temperature, sound, pollution levels, humidity and wind.
Future Combat Systems (FCS) was the United States Army's principal modernization program from 2003 to early 2009. Formally launched in 2003, FCS was envisioned to create new brigades equipped with new manned and unmanned vehicles linked by an unprecedented fast and flexible battlefield network. The U.S. Army claimed it was their "most ambitious and far-reaching modernization" program since World War II. Between 1995 and 2009, $32 billion was expended on programs such as this, "with little to show for it".
A motion detector is an electrical device that utilizes a sensor to detect nearby motion. Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. They form a vital component of security, automated lighting control, home control, energy efficiency, and other useful systems. It can be achieved by either mechanical or electronic methods. When it is done by natural organisms, it is called motion perception.
The Air Force Technical Applications Center (AFTAC), based at Florida's Patrick Space Force Base, is an Air Force surveillance organization assigned to the Sixteenth Air Force. Its mission is to monitor nuclear treaties of all applicable signatory countries. This is accomplished using seismic, hydroacoustic and satellite-detection systems alongside ground based and airborne materials collection systems.
A gunfire locator or gunshot detection system is a system that detects and conveys the location of gunfire or other weapon fire using acoustic, vibration, optical, or potentially other types of sensors, as well as a combination of such sensors. These systems are used by law enforcement, security, military, government offices, schools and businesses to identify the source and, in some cases, the direction of gunfire and/or the type of weapon fired. Most systems possess three main components:
The Fido explosives detector is a battery-powered, handheld sensory device that uses amplifying fluorescent polymer (AFP) materials to detect trace levels of high explosives like trinitrotoluene (TNT). It was developed by Nomadics, a subsidiary of ICX Technologies, in the early 2000s as part of the Defense Advanced Research Projects Agency's (DARPA) Dog's Nose program. The Fido explosives detector is considered the first artificial nose capable of detecting landmines in the real world. The device was named after its ability to detect explosive vapors at concentrations of parts per quadrillion, which is comparable to the sensitivity of a bomb-sniffing dog’s nose, i.e. the historical “gold standard” for finding concealed explosives.
The FCS Network - Brigade Combat Team (BCT) Network consists of five layers that deliver data to forward-deployed Army units.
Materials MASINT is one of the six major disciplines generally accepted to make up the field of Measurement and Signature Intelligence (MASINT), with due regard that the MASINT subdisciplines may overlap, and MASINT, in turn, is complementary to more traditional intelligence collection and analysis disciplines such as SIGINT and IMINT. MASINT encompasses intelligence gathering activities that bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT), Imagery Intelligence (IMINT), or Human Intelligence (HUMINT).
Radar MASINT is a subdiscipline of measurement and signature intelligence (MASINT) and refers to intelligence gathering activities that bring together disparate elements that do not fit within the definitions of signals intelligence (SIGINT), imagery intelligence (IMINT), or human intelligence (HUMINT).
Electro-optical MASINT is a subdiscipline of Measurement and Signature Intelligence, (MASINT) and refers to intelligence gathering activities which bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT), Imagery Intelligence (IMINT), or Human Intelligence (HUMINT).
Geophysical MASINT is a branch of Measurement and Signature Intelligence (MASINT) that involves phenomena transmitted through the earth and manmade structures including emitted or reflected sounds, pressure waves, vibrations, and magnetic field or ionosphere disturbances.
Diver detection sonar (DDS) systems are sonar and acoustic location systems employed underwater for the detection of divers and submerged swimmer delivery vehicles (SDVs). The purpose of this type of sonar system is to provide detection, tracking and classification information on underwater threats that could endanger property and lives. Further, this information is useful only to the extent that it is made available to authorities in time to make possible the desired response to the threat, be it deterrent or defensive action. Subsurface threats are a difficult problem, because reliable detection is available to date chiefly by use of high-resolution active sonar or trained dolphins or sea lions. The threat of an underwater terrorist attack is a concern to the maritime industry and port law enforcement agencies. Ports face a range of threats from swimmers, boat-delivered ordnance such as limpet mines and other forms of improvised underwater explosive devices. DDS systems have been developed to provide underwater security for ports, coastal facilities, offshore installations, pipelines and ships. Due to the variety of life and objects that exist under the water, it is desirable that a DDS system be capable of distinguishing between large sea mammals, shoals of fish; a ship's wake; a diver with an open circuit scuba set and a stealth diver with a rebreather. DDS systems have been developed that can be mounted on the seabed, on a pier or on the hull of a vessel. For complete port security these systems are integrated with the surface surveillance and security systems employed at ports, coastal facilities and offshore installations. Various systems provide specialized features to facilitate their use in port security systems including automatic detection features.
The Manned Ground Vehicles (MGV) was a family of lighter and more transportable ground vehicles developed by Boeing and subcontractors BAE Systems and General Dynamics as part of the U.S. Army's Future Combat Systems (FCS) program. The MGV program was intended as a successor to the Stryker of the Interim Armored Vehicle program.
Project Scorpion is a multinational military modernization program which uses military-run experimentation for acquisition of new armaments.

Counter-IED equipment are created primarily for military and law enforcement. They are used for standoff detection of explosives and explosive precursor components and defeating the Improvised Explosive Devices (IEDs) devices themselves as part of a broader counter-terrorism, counter-insurgency, or law enforcement effort.
Human sensing encompasses a range of technologies for detecting the presence of a human body in an area of space, typically without the intentional participation of the detected person. Common applications include search and rescue, surveillance, and customer analytics.
Unattended Transient Acoustic MASINT Sensor (UTAMS)Mortar, Rocket, Explosive Locator System is an acoustic localization sensor system developed by the Sensors and Electronic Devices Directorate (SEDD) of the U.S. Army Research Laboratory (ARL) in 2004. This technology is utilized to detect and isolate transient events such as mortar or rocket firings, munition impacts, and other explosive events. It consists of an array of acoustic sensor stations that are linked via radio to a receiving base. Each sensor has the ability to monitor hostile territory, international borders, and/or detect indirect weapon fire covertly with 24-hour surveillance. These small, inexpensive, non-imaging sensors can monitor large areas without a significant need for power sources and manpower.
