摘要
调频连续波合成孔径雷达(FMCW SAR)是一种具有体积小、重量轻、成本低、分辨率高等一系列优点的成像雷达,能装载于无人机和导弹等小型飞行器上。根据巡航导弹的特点,研究了装载于巡航导弹的FMCW SAR成像的空间几何模型和回波信号的特点,详细推导了FMCW SAR的信号处理过程,仿真结果表明FMCW SAR能实现高精度成像。
Frequency modulated continuous wave (FMCW) synthetic aperture radar (SAR) is a newly proposed imaging radar system. It has the advantages such as small cuhage, light weight, cost-effective, high-resolution, etc. FMCW SAR can be mounted on unmanned aerial vehicle (UAV), missile and other small aerial vehicle. Considering the characteristics of cruise missile, the spatial geometry model and the peculiarity of echo are researched. The signal processing of FMCW SAP, RD imaging algorithm was deduced in detail. The simulation result shows FMCW SAR is a kind of high resolution radar.
