Abstract: In a synthetic aperture radar system monitoring an area containing at least one moving target for identification, the target is equipped with an identification device, which receives the radar signal transmitted by the radar system, and transmits a processed radar signal obtained by modulating the incoming radar signal with a modulating signal containing target information, such as identification and status information, and by amplifying the modulated radar signal; the radar echo signal reflected by the monitored area and containing the processed radar signal is received and processed by a control station of the radar system to locate the target on a map of the monitored area, and to extract the target information to identify the target.

Abstract: In a synthetic aperture radar system (1) monitoring an area containing at least one moving target (2) for identification, the target (2) is equipped with an identification device (3), which receives the radar signal (RS) transmitted by the radar system (1), and transmits a processed radar signal (ES) obtained by modulating the incoming radar signal (RS) with a modulating signal (MODS) containing target (2) information (ID, MSG), such as identification (ID) and status (MSG) information, and by amplifying the modulated radar signal (RS); the radar echo signal (RES) reflected by the monitored area and containing the processed radar signal (ES) is received and processed by a control station (8) of the radar system (1) to locate the target (2) on a map of the monitored area, and to extract the target (2) information (ID, MSG) to identify the target (2).
