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

FIELD: radiolocation. SUBSTANCE: angular selector for double-range monopulse radar has two double-threshold decision-making units, two threshold decision-making units with zero threshold voltage, logic element determining equivalence and three-input logic AND gates. First double-threshold and threshold decision-making units are tied together with their signal inputs to input of selector to generate signal of angular error of first range and second double- threshold and threshold decision-making units are tied together with their signal inputs to input of selector to generate signal of angular error of second range. Outputs of both double-threshold decision-making units are connected directly and outputs of both threshold units via logic element determining equivalence to three-input logic AND gate which output is output of selector. EFFECT: elimination of angular ambiguity caused by multilobe form of antenna radiation pattern and direction finding characteristics. 3 dwg
