For radar dishes, a single, large, ball-shaped dome also protects the rotational mechanism and the sensitive electronics, and is heated in colder climates to prevent icing. The RAF Menwith Hill electronic surveillance base, which includes over 30 radomes, is widely believed to regularly intercept satellite communications.
The Sentinel A4 is a complete redesign of the sensor that uses digital processing and solid-state antenna modules based on gallium nitride (GAN) transmitters. The scalable modular architecture is shared with the long-range AN/TPY-4 radar, which has 1000 individually controlled elements and uses GPU computing for signal processing.
The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. [1] [2] The system offers instrumented detection at ranges on the order of 200 to 250 nautical miles (370 to 460 km; 230 to 290 mi) and has a wide variety of interference and clutter rejection systems.

Millimeter wave (mmWave) sensing is a non-contact system of using mmWave radar sensors to measure movement, acceleration, and angles as small as a fraction of a millimeter. [1] This system requires a mmWave radar sensor to transmit and receive pulses of millimeter electromagnetic wave energy, detecting targets and motion from the reflections it ...
As a tactical radar, the ELM 2084 is a mobile system consisted of the radar unit, a control module, a cooling unit and a power generator. It can be mounted on a variety of transport platforms. The radar was designed to accommodate medium range operational needs in the battlefield: detection, classification and tracking of targets.
Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
Once the radar detects a rocket, the system determines whether the rocket is headed toward a populated area. If so, it launches a missile to intercept and destroy the rocket.
