In the process of synthetic aperture radar (SAR) data acquisition, aircraft are susceptible to various disturbances during flight, resulting in the loss or destruction of azimuth echo data, which leads to blurring of SAR images. To solve the problem

The group condensation is a key process of the two-step method and is the guarantee of efficiency of the two-step method. However, the group condensation of the two-step method also reduces the energy resolution and leads to the calculation errors. T

Transient interference often submerges the actual targets when employing over-the-horizon radar (OTHR) to detect targets. In addition, modern OTHR needs to carry out multi-target detection from sea to air, resulting in the sparse sampling of echo dat

Multichannel spaceborne synthetic aperture radar (SAR) is a useful approach to overcome minimum antenna area constraint and achieve high-resolution and wide-swath imaging. For multichannel SAR imaging, the azimuth ambiguity is the principal problem,
