Abstract
In the conventional single-channel space-borne KaSAR system, wide swath and high resolution are difficult to be realized simultaneously. For this purpose, this paper combines range-dimensional DBF and TOPSAR to obtain SAR images. The DBF technology is used to carry out fusion processing of range-dimensional multi-channel echoes with wide swath and high SNR. TOPS mode can further obtain large scene...
