Дык, у "Фалкона"-то не тарелка, а конформные антенны
Здравствуйте, уважаемый В.Кашин!
Вот краткое описание РЛС:
EL/M-2075 Phalcon AEW radar
The EL/M-2075 Phalcon is a solid-state D-band conformal array radar system for use on a Boeing 707 and other aircraft. Phalcon is intended for airborne early warning, tactical surveillance of airborne and surface targets and intelligence gathering. It will also have the command and control capabilities needed to use this information.
The system uses six panels of phased-array elements: two on each side of the fuselage, one in an enlarged nosecone and one under the tail. Each array consists of 768 solid-state transmitting and receiving elements, each of which is weighted in phase and amplitude. These elements are driven by individual modules and every eight modules are connected to a transmit/receive group. Groups of 16 of these eight module batches are linked back to what is described as a prereceive/transmit unit, and a central six-way control is used to switch the pretransmit/receive units of the different arrays on a time division basis.
Each array scans a given azimuth sector, providing a total coverage of 360º. Scanning is carried out electronically in both azimuth and elevation. Radar modes include high PRF search and full track, track-while-scan, a slow scan detection mode for hovering and low-speed helicopters (using rotor blade returns) and a low PRF ship detection mode. These modes can be interleaved to provide multimode operation in any scanning sector. Typically, 2 to 4 second scan rates are used in high-priority sectors and 10 to 12 second rates in low-priority sectors.
