Description
technical field
[0001] The invention relates to the field of radar imaging, in particular to an arc aperture radar imaging method and radar based on antenna phase pattern compensation. Background technique
[0002] Synthetic Aperture Radar (SAR) is an all-time, all-weather, high-resolution imaging radar, which is widely used in the field of remote sensing. Since the SAR image has phase information, the non-contact and high-precision extraction of the deformation information of the imaging area can be realized through the interference processing of the SAR image sequence. In view of the above advantages of the SAR system, it has become one of the important means of ground deformation monitoring. However, traditional SAR systems are mostly carried on platforms such as satellites and aircraft, which makes the radar revisit time very long and cannot continuously monitor specific targets. Ground Based SAR (Ground Based SAR, GBSAR) is a miniaturized, low-cost SAR system that can...
