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

FIELD: radiolocation. SUBSTANCE: invention is related to angular selectors of radar targets and is used to reduce angular ambiguity of surveillance monopulse radar under condition of target following in transit. Angular selector for surveillance monopulse radar includes unit evaluating direction finding sensitivity, two threshold decision-making units ( PRB₁ and PRB₂ ) and logic AND gate with inverse and direct inputs. Unit evaluating direction finding sensitivity is connected with its inputs to outputs of surveillance monopulse radar for signal of angular error and angle of antenna turn and is connected with its output via PRB₁ and PRB₂ to inverse and direct inputs of logic AND gate having output for target indication signal in working range of angles and outside of its limits. EFFECT: enhanced selectivity by way of formation and usage of present smoothed evaluation of values of direction finding sensitivity in entire range of angular mismatch. 4 dwg
