In order to solve the contradiction between high-resolution and wide-swath for the
spaceborne single-channel SAR system, this paper proposes a new method based on …

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 …

A wide-swath SAR scheme based on displaced phase center azimuth multibeam is
presented in this paper. More than one azimuth sampling can be acquired during one pulse …

Multi-channel SAR can achieve high resolution and wide swath at the same time, which
overcoming the inherent limitations of conventional SAR system. Azimuth uniformly sampled …

In order to reduce the complexity of the receiving system for wideband signals, a novel
space-borne high-resolution synthetic aperture radar (SAR) system with the non-uniform …

With the increasing demands for higher resolution and wider swath in many applications of
Synthetic Aperture Radar (SAR), sliding spotlight mode has been presented. Here the …

The modern spaceborne SAR system requires both high resolution and wide swath, and the
conventional single channel spaceborne SAR system has a contradiction between the two …

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 …

High squint spotlight mode of spaceborne SAR can be used to achieve high resolution and
wide swath, and also can be used to acquire information of target from multi-azimuth …

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 …
