초록

A monopulse radar equipment is developed which comprises first and second radiators arranged in symmetrical positions with respect to the boresight axis to radiate radar pulses in a predetermined cycle and thus to produce first and second directional radiation patterns, a beam forming network for synthesizing in an in-phase and opposite-phase relation the first and second directional radiation patterns of the first and second radiations into sum and different patterns, and a multichannel receiver for forming from the sum and difference patterns an off-bo...
