ABSTRACT:
After each received signal in the same two antennas of the monopulse power feed system are inputted into a hybrid circuit, a sum signal .SIGMA. and a difference signal .DELTA. are formed, and they are demodulated in detection circuits, zero is outputted if the value of the sum signal .SIGMA. is equal to or smaller than the value of the difference signal .DELTA., otherwise the value subtracted the difference signal .DELTA. from the sum signal .SIGMA. outputted, in a signal processing section. Thus, beam compression and reduction of a side lobe are performed.
