The multiple azimuth angle spaceborne (MAAS) SAR can observe the region-of-interest
(ROI) with different azimuth angles during single pass, which can significantly increase the …

This paper reviews the novel azimuthal multi-angle spaceborne Synthetic Aperture Radar
(SAR) technique. First, the development status and trend of SAR satellites are analyzed, 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 …

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 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 …

This paper investigated the potential role of HAP in wide-area and staring SAR imaging.
Since it is necessary to suppress possible range ambiguities in wide-area SAR imaging, we …

Because the nearspace slow-moving platform borne synthetic aperture radar (SAR) can
realize high resolution imaging using low pulse repetition frequency (PRF), a full-aperture …

For SAR (Synthetic Aperture Radar) system, the high resolution (range/azimuth) and wide
swath are required constantly. It is challenge to achieve both high azimuth resolution and …

There are two most serious problems in the imaging mode of forward-looking SAR (F-SAR).
The first one is that the gradient of the Doppler frequency is very small and it is very difficult …

The new generation spaceborne SAR systems will be with high resolution and several work
modes. In this paper, a unified imaging algorithm for multimode spaceborne SAR with the …
