ABSTRACT:
The present invention concerns an airborne radar receiver for acquisition and tracking of a target providing two range-gates displaced during a search phase and comprising means for locking the range gates onto an echo receiver which is then tracked during a tracking phase. The receiver also comprises means for supplying a third gate accompanying the first two range gates and adjacent to the latter in the direction of the greater distances, and means for bringing all the gates back to zero when the third range gate encounters an echo the width of which is greater than a predetermined value corresponding to a target.
