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 AN/APG-78 Longbow is a millimeter-wave fire-control radar (FCR) target acquisition system and the Radar Frequency Interferometer (RFI), which are housed in a dome located above the main rotor. [4] [5] The radome's raised position enables target detection while the helicopter is behind obstacles (e.g. terrain, trees or buildings). The APG-78 ...
AN/SPS-64 Navigation radar, a surface navigation and search radar, made by Raytheon and used both commercially (brand name Mariner's Pathfinder) and by navies worldwide. [citation needed] AN/SPS-65 Development of AN/SPS-58 by Westinghouse as a low altitude radar that is part of the Mark 91 Fire Control System for the Sea Sparrow air defense ...
The radar measures the distance to the reflector by measuring the time of the round trip from emission of a pulse to reception, dividing this by two, and then multiplying by the speed of light. To be accepted, the received pulse has to lie within a period of time called the range gate .
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.
