The AN/SPS-67 is a short-range, two-dimensional, surface-search/navigation radar system that provides highly accurate surface and limited low-flyer detection and tracking capabilities.
The AN/SPS-67 is a solid-state replacement for the AN/SPS-10 radar, using a more reliable antenna and incorporating standard electronic module technology for simpler repair and maintenance. The AN/SPS-67 provides excellent performance in rain and sea clutter, and is useful in harbor navigation, since the AN/SPS-67 is capable of detecting buoys and small obstructions without difficulty.

The AN/SPS-67(V)1 radar is a two-dimensional (azimuth and range) pulsed radar set primarily designed for surface operations with a secondary capability of anti-ship-missile and low flier detection. The radar set operates in the 5450 to 5825 MHz range, using a coaxial magnetron as the transmitter output tube. The transmitter/receiver is capable of operation in several pulse width settings: a long (1.0 μs), medium (0.25 μs), or short (0.10 μs) pulse mode to enhance radar performance for specific operational or tactical situations. Pulse repetition frequencies (PRF) of 750,1200, and 2400 pulses/second are used for the long, medium, and short pulse modes, respectively. [1] The higher PRF settings coupled with the shortest pulse increases the resolution of the return and enables the radar operator/observer to discern or differentiate between a single large target or 2 smaller targets in close proximity to each other.
Radar is a system that uses radio waves to determine the distance (ranging), direction, and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. The term applies to radar systems in many domains like aviation, police radar detectors, navigation, meteorology, etc.
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).
A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics.
The AN/SLQ-32 is a shipboard electronic warfare suite built by the Raytheon Company of Goleta, California and The Hughes Aircraft Company. It is currently the primary electronic warfare system in use by U.S. Navy ships. Its operators commonly refer to it as the "Slick-32".
The AN/APG-66 radar is an X-band solid state medium range pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation for use in early generations of the F-16 Fighting Falcon. Later F-16 variants use the AN/APG-68 or the AN/APG-83. This radar was employed in all domestic and export versions of the F-16A/B models throughout the production. Subsequent upgrades have been installed in many varying aircraft types including the U.S. Customs and Border Protection's C-550 Cessna Citation, US Navy P-3 Orion, and Piper PA-42 Cheyenne II's.
The Type 360 is an air/surface search radar manufactured by Yangzhou Marine Electronic Instruments Research Institute (扬州船用电子仪器研究所)/ No. 723 Institute and is reportedly based on Selenia RAN-10S / SPS – 774. It is deployed on a number of new PLAN vessels, such as the Ma'anshan class frigate.
The JY-9 Radar is a mobile S band low altitude search radar intended for use in air defense, gap filling, airport surveillance, and coastal defense. It is designed for effective detection of targets at low altitude in both ECM and natural clutter environments. The general designer of the JY-9 is academician of Chinese Academy of Sciences Mr. Wu Manqing, the head of 38th Research Institute, who is also the general designer of the JY-8 Radar and of the radar systems for the KJ-2000 and KJ-200 early warning aircraft.
The AN/SPS-48 is a US naval electronically scanned array, air search three-dimensional radar system manufactured by ITT Exelis and deployed in the 1960s as the primary air search sensor for anti-aircraft warships. The deployment of the AN/SPY-1 and the end of the Cold War led to the decommissioning of many such ships, and many of these vessel's AN/SPS-48 sets were reused on aircraft carriers and amphibious ships where it is used to direct targets for air defense systems such as the Sea Sparrow and RIM-116 SAM missiles. Existing sets are being modernized under the ROAR program to AN/SPS-48G standard for better reliability and usability.
The AN/SPS-49 is a United States Navy two-dimensional, long range air search radar built by Raytheon that can provide contact bearing and range. It is a primary air-search radar for numerous ships in the U.S. fleet and in Spain, Poland, Taiwan aboard Oliver Hazard Perry-class frigates, Canada on its Halifax-class frigate and New Zealand on its Anzac-class frigates. It formerly served in a complementary role aboard Aegis cruisers with the AN/SPY-1 but the systems are currently being removed during routine upgrade with no replacement.
A radar system uses a radio-frequency electromagnetic signal reflected from a target to determine information about that target. In any radar system, the signal transmitted and received will exhibit many of the characteristics described below.
The AN/SPS-55 is a solid state surface search and navigation radar. It was developed by Cardion Electronics for the U.S. Navy under a contract awarded in 1971. It was originally developed for a class of ships known as Patrol Frigates, but it was also installed on numerous Cruisers, Destroyers, and Minesweepers. It is an I band radar and its antenna consists of two waveguide slotted arrays mounted back-to-back. One array provides linear polarisation and the other provides circular polarisation. Polarisation is user selectable and the circular polarised array is more effective in reducing returns from precipitation.
AN/SPQ-9A is a United States Navy multi-purpose surface search and fire control radar used with the Mk-86 gun fire-control system. It is a two dimensional surface-search radar, meaning it provides only range and bearing but not elevation. It is intended primarily to detect and track targets at sea level, on the surface of the water for either gun fire engagement or navigation. It can however, also detect and track low altitude air targets.
The AN/FPS-16 is a highly accurate ground-based monopulse single object tracking radar (SOTR), used extensively by the NASA crewed space program, the U.S. Air Force and the U.S. Army. The accuracy of Radar Set AN/FPS-16 is such that the position data obtained from point-source targets has azimuth and elevation angular errors of less than 0.1 milliradian and range errors of less than 5 yards (5 m) with a signal-to-noise ratio of 20 decibels or greater.
The AN/SPS-40 is a United States Navy two-dimensional, long range air search radar that is capable of providing contact bearing and range. It was replaced by the AN/SPS-49 on newer ships and on ships that received the New Threat Upgrade.
The AN/SPY-1 is a United States Navy 3D radar system manufactured by Lockheed Martin. The array is a passive electronically scanned system and a key component of the Aegis Combat System. The system is computer controlled and uses four complementary antennas to provide 360-degree coverage. The system was first installed in 1973 on USS Norton Sound and entered active service in 1983 as the SPY-1A on USS Ticonderoga. The -1A was installed on ships up to CG-58, with the -1B upgrade first installed on USS Princeton in 1986. The upgraded -1B(V) was retrofitted to existing ships from CG-59 up to the last, USS Port Royal.
The Mark 34 Gun Weapon System (GWS) is a component of the Aegis Combat System that is responsible for controlling and providing fire control to the 5" Mark 45 gun. It is used on the U.S. Navy Arleigh Burke-class destroyer and several later Ticonderoga-class cruisers. The Mk 34 GWS receives target data from the ship's sensors and off-ship sources, performs ballistic calculations, and produces gun control orders. The system is made up of the gun mount itself, the fire-control computer, and an optical sight.
