摘要
Abstract
Frequency-modulated continuous-wave synthetic aperture radar (FMCW SAR) combining FMCW technology and SAR techniques together, is a small size, low cost and high resolution imaging system. It can be extensively applied in both un-manned aerial vehicles and near space vehicles. For the conventional FMCW SAR, the contradiction between azimuth resolution and wide swath imposes restrictions on its application. FMCW carrier leakage has an impact on the detection range and swath. In order to overcome these limitations, the paper combines multiple azimuth beams (MAB) with FMCW SAR, and presents a high-resolution wide-swath imaging method using displaced phase centers (DPC) based on range Doppler algorithm. Finally, the simulation test verifies the effectiveness of the high-resolution wide-swath imaging method.关键词
