Application of the TRMC processing chain to SAR/ISAR imaging

In this paper we present the application of a single algorithm (TRMC) for different radar imaging techniques (SAR/ISAR), since in both cases the aim of the processing is to compensate the unwanted effects of pure translational and rotational relative motion between radar and target. The proposed techniques for estimation and compensation of these two motion components are briefly discussed and their extensive application to real radar data for different classes of targets (ships, aircrafts, ground) is presented. Results show that the proposed processing is particularly effective in case of nonuniform rotation-rate during the Coherent Processing Time (CPT) considered for imaging The low computational cost and the effectiveness of the proposed algorithms make them suitable and convenient for real-time applications even for compact and low-weight radar systems to be fitted onboard UAV or other airborne platforms.
