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 …

Multichannel synthetic aperture radar (SAR) is a breakthrough given the inherent limitation
between high-resolution and wide-swath (HRWS) faced with conventional SAR. This paper …

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 …

Abstract In bistatic spaceborne High-Resolution Wide-Swath SAR systems (HRWS-SAR),
the azimuth reconstruction to obtain a uniform sampling signal or Doppler spectrum is a …

Multi-channel SAR enables wide swath with high azimuth resolution. Azimuth non-uniform
sampling will occur due to the nature of the orbit in the multi-channel SAR. In order to use …

Abstract Synthetic Aperture Radar (SAR) with multiple antennas can realize High-Resolution
Wide-Swath (HRWS) imaging, improve Signal to Noise Ratio (SNR) and improve ambiguity …

The technique of azimuth multichannel synthetic aperture radar (SAR) system has become a
potential solution to the irreconcilable conflict between high-resolution and wide-swath …

Spaceborne multichannel synthetic aperture radar (SAR) is an effective means to realize
high-resolution and wide-swath imaging. However, for spaceborne multichannel SAR …

Unlike the traditional multichannel synthetic aperture radar (SAR) 3-D reconstruction
technology, the single-channel SAR with two synthetic apertures in the vertical and …

Azimuth multichannel SAR system is a promising solution to achieve high-resolution and
wide-swath (HRWS) imaging for spaceborne synthetic aperture radar (SAR) system. These …
