An object at height h above the ground and slant range R forms an angle α that can be calculated through sin α = h / R.By re-arrangement, R = h / sin α, or R = h csc α. The radar equation states that the signal received from an object, P e, varies inversely with the 4th power of range and directly as the square of the antenna gain, G, such that P e ~ G 2 / R 4.
The Fan Song radars are capable of tracking 6 targets at a time, and can guide up to three missiles at once to it. The radars feature two orthogonal antennas, one for azimuth and one for elevation, which can operate in a track-while-scan mode. These antennas transmit 10 × 2 degree or 7.5 x 1.5 degree beams and perform a 'flapping' motion as ...
SJ radar was a type of S band (10-cm) radar set used on American submarines [3] during the Second World War. [4] The widespread use of the SJ radar, combined with the very low use of radar in the Imperial Japanese Navy, gave great operational flexibility to the United States Navy's submarine campaign in the Pacific Ocean.

Tethered Aerostat Radar System in New Mexico. The first aerostats were assigned to the United States Air Force in December 1980 at Cudjoe Key, Florida.During the 1980s, the U.S. Customs Service operated a network of aerostats to help counter illegal drug trafficking.
1.2 kW AN/SPQ-9A (sometimes pronounced as "spook nine") is a United States Navy multi-purpose surface search and fire control radar used with the Mk-86 gun fire-control system (MK86 GFCS) . It is a two dimensional surface-search radar, meaning it provides only range and bearing but not elevation .
SMART-S Mk2 [2] [5] [4] (Signaal Multibeam Acquisition Radar for Tracking, S band Mk2) is a naval medium to long-range air and surface surveillance multibeam passive electronically scanned array 3D radar designed by Thales Nederland, [6] formerly Hollandse Signaalapparaten (Signaal). While the original SMART-S radar was only produced in small ...
The first radar of the radar family AN/APG-76 belongs to is AN/APQ-92, which equipped A-6A.AN/APQ-92 is a search and navigational radar, with function called search radar terrain clearance (SRTC) to generate a synthetic terrain display on the pilot's Vertical Display Indicator (VDI), which is a large cathode ray tube (CRT) display in the center of the pilot's console, right under the gun sight.
