FIELD: physics, navigation.SUBSTANCE: invention relates to radar and can be used in surveillance monopulse radar stations. The said result is achieved due to that a multichannel receiver comprises an angle sensor, an angular discriminator of receiver-amplifier channels, each consisting of the first clipper, the first delay line, a controlled attenuator and an optimum filter, as well as a heterodyne frequency converter, a minimum computer. Furthermore, each receiver-amplifier channel includes an adder, the second clipper, a synchronous detector, a band-pass filter, an amplitude detector, the second delay line and a ratio computer. The listed components are interconnected in a certain manner.EFFECT: high accuracy of direction-finding.1 dwg |
