GROUND BASED SYNTHETIC APERTURE RADAR (GBSAR) WITH TRANSMITTING AND RECEIVING MULTIPLE ANTENNAS (MIMO) AND USING THE PROCESSING TECHNIQUE CALLED COMPRESSIVE SENSING (CS)

摘要

Ground radar apparatus comprising: at least a main radar unit (U) provided with at least a transmitting unit (TX) and at least a receiving unit (RX); two parallel linear guides G1 and G2 with antenna securing systems; NTX antennas connected to the transmitting unit TX; NRX antennas connected to the RX transmitting unit. This radar is a MIMO (Multiple Input Multiple Output) that operates as an interferometric GBSAR (Ground Based Synthetic Aperture Radar) exploiting a particular implementation of the processing technique called Compressive Sensing (CS). In a further configuration of the same radar the parallel linear guides are three, in this way it is possible to acquire two different interferograms of the same scenario that allow to calculate two different components of the possible displacement of the targets.
