Abstract

A target identification system comprises a high-resolution synthetic-aperture radar system (1-6). After rejecting the background details supplied by the processor (10) of the SAR, only the coordinates of potential targets being retained, the removed material is replaced by more reliable background details originating from a pre-recorded map (19). This enables a human operator to take any desired decision as regards the reality of the targets. <IMAGE>
