| titleOfInvention | Strabismus spotlight SAR imaging method, device, equipment and storage medium with variable PRI |
| abstract | The application discloses a squint spotlight SAR imaging method, device, equipment and storage medium with variable PRI. It relates to the technical field of synthetic aperture radar. The technical solution includes: recovering the range migration form of the radar echo data in the variable PRI mode; removing the azimuth spectrum aliasing and range time domain aliasing of the radar echo data; restoring the uniform sampling of the azimuth signal of the radar echo data and perform phase compensation on the restored radar echo data; perform imaging on the radar echo data after phase compensation. According to the technical solution of the embodiment of the present application, under the condition of ensuring the calculation efficiency, the undersampling under the condition of non-uniform azimuth signal of the radar echo data in the variable PRI mode can be restored, thereby improving the processing of the frequency domain imaging algorithm efficiency. |
