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 …

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 …

Incorporated with digital beamforming processing, along-track multi-channel spaceborne
SAR systems are promising in High-Resolution and Wide-Swath (HRWS) imaging by …

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 …

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

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 …

To realize the high-resolution wide-swath mapping capability of spaceborne SAR, this paper
presents a parabolic cylinder reflector based MIMO SAR system. According to the analysis of …

Airborne SAR imaging processing needs to estimate motion error to compensate non-ideal
trajectory. In this paper, a subaperture imaging scheme for wide azimuth beam airborne …

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 …
