Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external ("offboard") source—as it reflects off the target. Semi-active missile systems use bistatic continuous-wave radar.
The SAMPSON is a multi-function dual-face active electronically scanned array radar produced by BAE Systems Maritime. It is the fire control radar component of the Sea Viper naval air defence system. The Sea Viper system is also known as PAAMS(S) to denote the use of the SAMPSON radar and to distinguish it from the PAAMS system on the Franco-Italian Horizon-class frigate.
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers.
The Delhi-class destroyers, also known Project 15 are a class guided-missile destroyers of the Indian Navy. Three ships of this class are in active service. The Delhi-class vessels were the largest vessels to be built in India at the time of their commissioning. The ships were built by Mazagon Dock Limited (MDL) at a cost of ₹750 crore each.
A fire-control radar (FCR) is a radar that is designed specifically to provide information to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as narrow beam radars, targeting radars, tracking radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar.
The Talwar-class frigates or Project 11356 are a class of stealth guided missile frigates designed and built by Russia for the Indian Navy. The Talwar-class guided missile frigates are the improved versions of the Krivak III-class frigates used by the Russian Coast Guard. The design has been further developed as the Admiral Grigorovich-class frigate for the Russian Navy. Six ships were built in two batches between 1999 and 2013.
The Kresta II class, Soviet designation Project 1134A Berkut A, was a class of guided missile cruiser built by the Soviet Union for the Soviet Navy. The NATO lists the class as "cruisers" mainly due to the Metel anti-ship missile system capable to strike not only submarines but also surface vessels. They were succeeded by the larger Kara class cruisers.
The S-75 is a Soviet-designed, high-altitude air defence system. It is built around a surface-to-air missile with command guidance. Following its first deployment in 1957 it became one of the most widely deployed air defence systems in history. It scored the first destruction of an enemy aircraft by a surface-to-air missile, with the shooting down of a Taiwanese Martin RB-57D Canberra over China on 7 October 1959 that was hit by a salvo of three V-750 (1D) missiles at an altitude of 20 km (66,000 ft). This success was credited to Chinese fighter aircraft at the time to keep the S-75 program secret.
The Type 051C destroyer is a long-range air-defence guided-missile destroyer built by China in its ongoing effort to create a true blue water navy. The ship uses the hull design of the older Type 051B, but is equipped with the advanced Russian S-300FM air defence missiles systems. Currently, two ships of this class have been launched and deployed by People's Liberation Army Navy North Sea Fleet.
The Saab Giraffe Radar is a family of land and naval two- or three-dimensional G/H-band passive electronically scanned array radar-based surveillance and air defense command and control systems. It is tailored for operations with medium- and Short Range Air Defense (SHORAD) missile or gun systems, or for use as gap-fillers in a larger air defense system.
Track-while-scan (TWS) is a mode of radar operation in which the radar allocates part of its power to tracking a target or targets while part of its power is allocated to scanning. It is similar to but functions differently in comparison to its counterparts range-while-search (RWS), long range search (LRS), air combat mode (ACM), velocity search with ranging (VSR) and combined radar mode (CRM). In track-while-scan mode the radar has the ability to acquire and lock/track multiple targets while simultaneously providing a view of the surrounding airspace, which in turn aids the pilot and or operator in maintaining better situational awareness.
The Sovremenny class, Soviet designation Project 956 Sarych (buzzard), is a class of anti-ship and anti-aircraft guided-missile destroyers of the Soviet and later Russian Navy. The ships are named after qualities, with "Sovremenny" translating as "modern" or "contemporary". Most of the ships have been retired from active service and one converted into a museum ship in 2018; as of 2021 three remain in commission with the Russian Navy with several in overhaul. Four modified ships were delivered to the People's Liberation Army Navy, and remain in service.
Cooperative Engagement Capability (CEC) is a sensor network with integrated fire control capability that is intended to significantly improve battle force air and missile defense capabilities by combining data from multiple battle force air search sensors on CEC-equipped units into a single, real-time, composite track picture. This will greatly enhance fleet air defense by making jamming more difficult and allocating defensive missiles on a battle group basis.
The HQ-17 is an all-weather, low to medium altitude, short-range surface-to-air missile system derived from the Tor-M1.
The AN/SPG-60 is a United States tracking radar that is part of the MK-86 Gun Fire Control System (GFCS). It is used for air tracking and on some MK-86 configurations it is also used for illumination for RIM-24 Tartar and RIM-66 Standard missiles. Though the radar is primarily an air tracking radar, the SPG-60 radar can be used for surface tracking. With the boresight mounted camera, the radar could also be used as a sight for optical tracking, optical engagement and damage assessment.
