线性调频信号（LFM）是雷达信号处理中的常见信号形式。

雷达成像中通过距离和方位2个方向的脉冲压缩实现高分辨成像。

附件中对这一技术的实现和误差分析进行了MATLAB仿真。-LFM (LFM) radar signal processing is a common signal format. Radar imaging distance and direction through the direction of two pulse compression to achieve high-resolution imaging. Annex to the realization of this technology and error analysis of MATLAB simulation carried out.
