| Rappel du premier message :IAI Phalcon 707    | Citation: | The AWE&C phased array radar replaces the conventional rotodome radar. It is mounted either on the aircraft fuselage or on top of the aircraft inside a stationary dome, providing full 360° coverage. This electronically steered beam radar delivers a tremendous advantage over mechanical rotating antenna, as it supports the tracking a high maneuvering targets. The radar can detect even low flying objects from distances of hundreds of kilometers, day and night, under all weather conditions. Verification beams sent at specific, individual, newly detected targets eliminate false alarms. Moreover, track initiation is achieved in 2 to 4 seconds as compared to 20 to 40 seconds with a rotodome radar
The IFF system employs solid state phased array technology to perform interrogation, decoding, target detection and tracking. A monopulse technique is used to implement azimuth measurement. The IFF data is automatically correlated with the phased array radar.
The ESM/ELINT system receives, analyzes and locates radar signals, covering 360o. It combines high sensitivity with high probability of intercept, and achieves excellent accuracy in bearing measurement. The system uses narrow-band super-heterodyne receivers and wide-band instantaneous frequency measurement (IFM) techniques to provide very high accuracy and probability of intercept of airborne and surface emitters. Very high bearing accuracy for all received signals is achieved through Differential Time of Arrival (DTOA) measurements. The system also collects and analyzes ELINT data.
The PHALCON's CSM/COMINT receives in UHF, VHF and HF, rapidly searching for airborne, shipborne or ground communications signals of interest. Selected radio nets can be monitored for signal activity. A DF capability locates targets. Detected signals can be assigned to monitoring receivers instantaneously. The system makes extensive use of computers to reduce the load on operators.
