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).

Abstract: It is proposed an equalization and precompensation system for TDMA communication and its application to the DECT system, which is able to enlarge the coverage area provided by a single base station in a wireless system through electronic procesing performed at the base station only, and to enhance the transmission quality of a wireless system through electronic processing performed at the base station only, in addition or in alternative to the coverage area enlargement of the individual base station, comprising a processor (P) inserted in the base station only, and replacing the direct links commomnly used to connect the modulation (MO) and the demodulation (DEM) sections respectively with the transmitting and receiving sections and containing channel estimation subsystems (CES), equalization (EQS) and precompensation (PCS) subsystems in order to be effective both for uplink and downlink.
