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 …

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 …

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 …

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 …

The multiple‐input multiple‐output (MIMO) technique can improve the high‐resolution wide‐
swath imaging capacity of synthetic aperture radar (SAR) systems. Beamspace MIMO‐SAR …

In airborne synthetic aperture radar (SAR), the arbitrary aircraft maneuvers significantly
degrade the achievable performance of the imaging system. Compared with other SAR …

Owing to the existence of high‐order motion parameters and vertical velocity, severe range–
azimuth coupling and two‐dimensional spatial variability of the imaging parameters degrade …

Since the United States launched the first synthetic aperture radar satellite in 1978, it has
attracted widespread attention because of its ability to obtain high-resolution images of …

Based on the problem that side-looking SAR can not image in flight direction with high
azimuth resolution, an innovative forward-looking SAR system is studied. The operation …
