ABSTRACT:
Multichannel synthetic aperture radar (SAR)
in azimuth can resolve the contradiction between high resolution and wide swath
faced with traditional SAR imaging. However, channel errors will degrade the
performance of imaging. This paper compares the performances of four channel error
estimation algorithms under different clutter distributions and SNR conditions.
Further, explanations are given for performance differences of the four
algorithms, which provide evidence for method selection in engineering applications.
