摘要
Abstract
Firstly, an airborne FMCW SAR test system is designed and analyzed, and the design methods and main principles of all parts of the system are explained in-depth.Based on the system, a flight test to validate the performance was conducted.Then,the characteristics of echo signal and imaging method of FMCW SAR are analyzed, and the influence on echo signal owing to the con-stant movement during the pulse sweep time was revealed, and the influence on imaging was quantitatively pointed out, and the re-vised range Doppler imaging algorithm is used to compensated this effect.At last, the performance and validity of the system and the image reconstruction algorithm designed in this paper are verified by the real flight experiment data.关键词
