A radar system and a weapon system to combat helicopters

摘要

The radar system essentially comprises:- Means for emitting a phase-encoded shaft via n of uniformly distributed points in time;- Means, in order to carry out in succession on the receiving side of the following operations:a filtering which is adapted to the broadcast code;a time / frequency - reaction over n successive sequence periods, in order to realize a doppler filtering;a suppression of those output to go of the doppler filter, the frequency in punctiform or quasi point correspond to the cone-shaped echoes;an inverse time / frequency - reaction, after which the helicopter wings - echoes are detected.The weapon system comprises a flying body, which in a first phase by the radar system commands via remote expensive and, in a second phase, by a target such apparatus is directed.
