Simulation of Multi-channel SAR Raw Data Based on Real Single Channel SAR Data

This paper presents a multi-channel SAR raw data simulation method that is used to develop, verify and evaluate the multi-channel SAR/GMTI technique. The simulated data are generated by superimposing multi-channel clutter data formed from real single SAR data and multi-channel moving targets data obtained through computer simulation. This is a compositing method, has cost benefits and greater fidelity. The compound data are tested with R-D imaging algorithm, DPCA technique and channel calibration technique proposed in reference. The results show the high quality of this multi-channel SAR raw data simulation method
