ABSTRACT:
A system for the automatic correction of the nodding elevation errors for radars tracking targets at low height, comprising in a conventional mode a receiving and transmitting group associated with an intermediate frequency channel and with an antenna servo in azimuth and elevation, having a channel of azimuth error and a channel of elevation error, comprising means for detecting the variations of the amplitude of the echo signal due to the multiple reflection effected at low height and means for subtracting the signal formed by said variations from the channel of elevation error of the antenna servo.
