Effect on SAR Calibration from Transponder Time-Delay
-
摘要: 该文研究了有源转发器延时对距离向压缩信号、方位向压缩信号幅度和相位的影响；通过数据仿真，分析和讨论了不同分辨率、不同时延长度的情况下，有源转发器延时对点目标成像位置、主瓣及旁瓣的影响，并给出有源转发器时延设置时需要考虑的因素。Abstract: The effect of transponder time-delay on amplitude and phase of both range-compressed and azimuth-compressed signal are researched. Through simulation, the impact of transponder time-delay on imaging location, main-lobe, side-lobe of point target pulse response are analyzed and discussed under different resolution, different length of time-delay. Besides, the factors which need to be taken into consideration during time-delay setting are presented.
