Abstract :
With the rapid developing of synthetic aperture radar (SAR) in recent year, multi-channel receive technology is widely applying in wide-swatch SAR, high resolution SAR, GMTI, InSAR, multi-band and multi-polarization SAR. In this paper, have a deeply discussion on equalizing between channels in wideband multi-receive aperture system when amplitude imbalance and phase non-uniform. Take a three receive aperture GMTI system as example, detail process is present, step by step from GMTI system design block diagram to final processing result. Measured data processing results validate effectiveness of the method.
