Device for the elimination of n.sup.th trace moving echoes and interference echoes in a radar

摘要

A device for the elimination of n.sup.th trace moving echoes and radar interference echoes in a radar system operating by bursts and comprising a display device for moving targets. The device comprises means for detecting first and n.sup.th trace echoes of which the amplitudes exceed, respectively, two given thresholds S.sub.1 and S.sub.2, and means for comparing these echoes with each other. The device finds particular utilization in a surveillance radar or in a radar landing system operating by pulses.
