The AN/FRD-10 is a United States Navy circularly disposed antenna array (CDAA), built at a number of locations during the Cold War for high frequency radio direction finding and signals intelligence. In the Joint Electronics Type Designation System , FRD stands for fixed ground, radio, direction finding. 14 sites were originally constructed as ...
Precision approach radar or PAR is a type of radar guidance system designed to provide lateral and vertical guidance to an aircraft pilot for landing, until the landing threshold is reached. [1] Controllers monitoring the PAR displays observe each aircraft 's position and issue instructions to the pilot that keep the aircraft on course and ...
The AN/TPS-75 is a transportable passive electronically scanned array air search 3D radar produced in the United States. It was originally designated the TPS-43E2. Although the antenna is a radically new design from the TPS-43, the radar van itself, which houses the transmitter, receiver processors, and displays is very similar to the older TPS ...
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.

An experiment on a similar antenna at 11.8 GHz was reported by NASA researchers in 1989. 5% 3 dB bandwidth and −16 dB sidelobe level were measured. [ 1 ] Until the 1980s, the Fresnel zone plate antenna was regarded as a poor candidate for microwave applications .
This antenna has fixed cell delays, configured by different cutout sizes in each cell, as can be seen in the top-right inset. Larger cutouts produce the dark rings visible in the overview. A reflectarray antenna (or just reflectarray) consists of an array of unit cells, illuminated by a feeding antenna (source of electromagnetic waves).
AN/MPN-25 ITT product that scans the PAR coverage area and capable of scanning 360 degree using the same antenna. The system then process the raw target data to form a data word sending it to a computer display operating on Solaris. It is a 30 nmi (56 km) asr coverage and 20 nmi (37 km) PAR coverage.
