TRANSCEIVER ANTENNA SYSTEM FOR RADAR STATION

摘要

active phased-out antenna arrays; radar stations of mobile equipment. SUBSTANCE: transceiver antenna system has two one-dimensional active phased-out transceiver antenna arrays 11 mounted horizontally and relatively orthogonaly each incorporating transceiver modules; each module has two radiators connected through switch to first sides of circulator whose second sides are connected to inputs of limiters; outputs of the latter are connected to inputs of low-noise amplifier whose outputs are connected to first sides of transmit-receive switches ; second sides of the latter are connected to inputs of power amplifiers whose outputs are connected to third sides of circulator; third sides of switches are connected to inputs of phase shifters whose outputs are connected to N-inputs (outputs) of switchgear; first side of switch is connected to that of circulator, its second and third sides, to inputs of radiators. System also has vertically mounted one-dimensional phased-out receiving antenna array with receiver modules each incorporating several radiators whose outputs are connected to inputs of multiple-side switch; output of the latter is connected to input of limiter whose output is connected to input of low-noise amplifier; output of the latter is connected to input of phase shifter whose output is connected to one of M inputs of summing amplifier. EFFECT: enlarged functional capabilities; reduced cost. 4 dwg
