FIELD: physics; radio. ^ SUBSTANCE: present invention relates to radar and is meant for increasing angular resolving power of radar stations and its regulation with simultaneous side lobe suppression of the directional pattern. The proposed device contains an antenna, whose inputs/outputs are connected to a generator of composite and differential signals, the output of which is connected to the input of a "transmit-receive" switch, the other input of which is connected to the output of a transmitter, a composite signal channel, comprising an amplitude detector, as well as differential signal channel, comprising an amplitude detector, a subtractor, video amplifier, limiter, the output of which is the output of the device and a controlled attenuator. The output of the "transmit-receive" switch is connected to the input of the amplitude detector of the composite signal channel, the output of which is connected to the first input of the subtractor. The output of the generator of composite and differential signals is connected through the controlled attenuator to the input of the amplitude detector of the differential signal channel, the output of which is connected to the second input of the subtractor, the output of which is connected through the video amplifier to the input of the limiter. ^ EFFECT: simplification of the circuit of the device. ^ 1 dwg |
