摘要
线性调频连续波(LFMCW)合成孔径雷达(SAR)因体积小,重量轻,成本相对低,成为近来研究的热点。连续波SAR的回波信号通常经过相干解调处理。针对其独特的应用背景和信号模型,对现有的各种成像处理算法进行了讨论和比较,总结出其优缺点及应用范围。并对LFMCW-SAR今后的发展提出了展望。
Linear Frequency Modulated Continuous Wave（LFMCW）-Synthetic Aperture Radar（SAR） has become a focus in recent researches, due to its compactness and low cost. This paper analyses and compares various imaging algorithms, based on the special application background and signal model derived from its dechirped raw data. Then the advantages, disadvtanges and application fields of the algorithms are presented. Future development of LFMCW SAB is prospected.
