Ultra-high spatial resolution is an important development direction of spaceborne synthetic
aperture radar (SAR). The finer the resolution, the more details can be obtained from the …

The range resolution is restricted by signal bandwidth. Besides, the side lobes will influence
image's contrast or even lead to imaging failure. In this paper, single-snap MUSIC was put …

In marine synthetic aperture radar (SAR) remote sensing images, the land and ships often
only occupy part of the images, and the rest are ocean or coastal backgrounds. Existing SAR …

For azimuth multichannel synthetic aperture radar (SAR), unavoidable inconsistency errors
between channels can degrade SAR image quality severely, leading to possible ghost …

In order to guarantee the image quality of ultra-high resolution spaceborne SAR, highly
precise phase and amplitude response of system is needed via calibration. Since this kind of …
