High-resolution and wide-swath (HRWS) synthetic aperture radar (SAR) imaging with azimuth multi-channel always suffers from channel phase and amplitude errors. Compared with spatial-invariant error, the range-dependent channel phase error is intracta

The Doppler information in complement to the intensity of radar backscatter has been verified useful for ocean synthetic aperture radar (SAR) applications. An accurate estimate of the ocean surface motions requires an accurate estimate of the Doppler
