摘要
调频连续波(FMCW)合成孔径雷达(SAR)因其体积小、重量轻、成本低及分辨率高等特点越来越受到关注。详细分析了FMCW SAR构成原理和距离维成像过程,提出了对抗FMCW SAR的措施。
There is a growing interest in the frequency modulated continuous wave（FMCW） synthetic aperture radar （SAR） for its advantages such as small cubage, light weight, low cost and high resolution. This paper analyzes the composition principle and imaging process in range direction in detail,presents the countermeasure to FMCW SAR.
