Brief description of the object of the performance of a radar in the presence of echo backscattered diffuse

摘要

The present invention relates to a method of detecting targets by a radar in the presence of echoes are a diffuse, the targets being designated, according to a theoretical location of the targets a priori, at a distance d with a range of inaccuracy δd and radial speed vr with a range of inaccuracy δ vr, the radar pulse compression type, emitting at the targets a wave in the form of a train of pulses... E, e,.. of the recurrence frequency fr, noise b carried by the wave, the radar comprising a detector of the echoes received, tenderness, the method consists in determining the recurrence frequency fr minimizing in the field of inaccuracy of designation in distance ad and in the radial velocity δv τ, on the one hand, the loss of signal of the echo returned by the target and, on the other hand, the desensitization of the radar detector for the backscattered by the clutter echoes. Applications: airborne radars, missile homing heads.
