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 …

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 …

Up to now, multiple innovative spaceborne synthetic aperture radar (SAR) imaging schemes
have been demonstrated for high resolution or/and wide swath coverage. Different imaging …

The precise motion compensation is a crucial issue for high-resolution airborne SAR
imaging, which is especially important for SAR imaging under airborne small platform or …

In the high resolution SAR, the effect of motion error at the azimuth direction is more severe.
Though the traditional Phase Gradient Autofocus (PGA) algorithm can be used to estimate …

The challenge in the imaging of high-squint-mode synthetic aperture radar (SAR) mounted
on maneuvering platforms is the azimuth dependence of both the range migration and the …

Synthetic aperture radar (SAR) techniques are typically used to achieve a high azimuth
resolution, but conventional monostatic SAR is not applicable in forward direction because …

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 …

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 …

The linear range walk yields a significant range-azimuth coupling effect in a highly squinted
synthetic aperture radar (SAR). Although the linear range walk correction (LRWC) technique …
