摘要
机载遥感微波成像雷达在地球观测特别是在城市应用中起着非常重要的作用,线性调频连续波雷达设备的高可靠性和紧凑性、低成本使得其适于机载系统多次重复应用,分析了连续波线性调频雷达构成机载合成孔径雷达的优点和应用环境,分析了连续波线性调频合成孔径雷达(SAR)的信号设计和相应的信号处理方法,给出了相应的仿真结果,通过仿真可以看出,连续波SAR具有较好的空间分辨力。
Airborne microwave imaging Radar for remote sensing plays an important role in earth observation, especially in the application to cities. Linear frequency modulation continuous wave (LFMCW) radar with the feature of high reliability and compactness is suitable for multiple applications in airborne radar. The advantages and application environment of LFMCW SAR is analyzed in this paper, and the methods of signal design and signal processing in LFMCW SAR are studied. A point target simulation result is given that shows LFMCW SAR has good space resolution.
