GROUND SURVEILLANCE AIRPORT RADAR AND RADAR INSTALLATION

摘要

FIELD: navigation. SUBSTANCE: ground surveillance airport radar includes one immobile antenna for electron scanning of control area by azimuth in horizontal plane, radiation source and means for reception/transmission of superhigh-frequency signal with circulator, transmission channel, reception channel and means for division of mentioned reception channel into elements receiving signal of sum and one signal as minimum of difference. First and second receiving elements receive correspondingly signal of sum and signal of difference with change of frequency and generate their output signals coded in digital form. Digital signals coming from first and second receiving elements are processed for radar detection of objects or targets in controlled area. EFFECT: simplicity and reduced cost of operation of surveillance airport radar. 21 cl, 31 dwg
