DEVICE FOR THE ELIMINATION OF N.SUP.T.SUP.H TRACE MOVING ECHOES AND INTERFERENCE ECHOES IN A RADAR

摘要

ABSTRACT OF THE DISCLOSUREA device for the elimination of nth trace movingechoes and radar interference echoes in a radar systemoperating by bursts and comprising a display device formoving targets. The device comprises means for detectingfirst and nth trace echoes of which the amplitudes exceed,respectively, two given thresholds S1 and S2 , and meansfor comparing these echoes with each other. The devicefinds particular utilisation in a surveillance radar or ina radar landing system operating by pulses.
