Nonuniform sample of SAR signal will bring the noise into the signals, and thus mix the
spectrum of the echo signals with that of the noises, increase ambiguity of the signals, and …

High-resolution and wide-swath synthetic aperture radar (SAR) images can be obtained by
multichannel sampling. However, a nonoptimum pulse-repetition frequency is associated …

The azimuth multichannel imaging scheme with the large receive antenna divided into
multiple sub-apertures usually leads to azimuth non-uniform sampling, and echoes from all …

The technique of multiple apertures in azimuth enables a wide swath synthetic aperture
radar (SAR) with a high azimuth resolution. In a traditional multi-channel SAR system, if the …

Azimuth multi-channel synthetic aperture radar has been widely studied to realize high
resolution wide swath imaging. Spectrum reconstruction algorithm deals with the main-lobe …

This paper proposes a 1-bit Synthetic Aperture Radar (SAR) imaging method based on a
