ANGULAR SELECTOR FOR SURVEILLANCE MONOPULSE RADAR Russian patent published in 2002 - IPC

FIELD: radiolocation. SUBSTANCE: delay line of radar is connected in series with output of angular selector to transmit signal of angular error. Delay line is connected with its input and output through adder and null detector connected in series to control input of make key. Tap from center of delay line is connected through mentioned key and modulus indicator to signal input of threshold solver that has output of signal of target indication in working range of angles or beyond its limits. EFFECT: elimination of angular ambiguity while tracking targets. 3 dwg
