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

FIELD: radiolocation. SUBSTANCE: angular selector for surveillance single-pulse radar includes threshold decision-making unit to eliminate angular inefficiency while tracking targets en route. It is also supplemented with weight discrete adder over sliding interval with output for signal of indication of target in working range of angles and beyond its limits. Weight discrete adder is connected with its input to output of signal of angular error of surveillance single-pulse radar and with its output to signal input of threshold decision-making unit. EFFECT: elimination of angular ambiguity by a priori known differences of signal of angular error in major and minor equal- signal zones of direction-finding characteristic. 3 dwg
