Phase gradient SAR image focusing was demonstrated to provide well-focused imagery; cross-range smearing of the imagery was significantly reduced, resulting in higher probability of correct classification as demonstrated by a 20+ target model-based classifier. HDI processing was demonstrated to improve the image quality of complex SAR imagery; the effective resolution of SAR imagery was shown to be increased as demonstrated by the improved Pcc achieved by a ten-target template-based classifier. 2D FFT image formation processing of interrupted SAR phase-history data was shown to yield SAR imagery containing significant artefacts and degraded image quality; CS-based image formation processing (BPDN) was shown to mitigate these image artefacts and produced complex SAR imagery having excellent image quality.
