| 摘 要： | 线性调频连续波（LFMCw）雷达具有距离和多普勒频率分辨率高，结构简单，体积小，重量轻和良好的低截获概率特性，得到了广泛的应用。对线性调频连续波雷达的目标回波信号进行分析，使用差拍一频谱分析-MTD的方法进行仿真，从回波信号中提取目标的相位信息，从而获取目标的距离和速度信息，该方法可有效地抑制固定杂波，方便动目标检测。

| Abstract: | Characterized by high resolution for distance and doppler frequency,simple structure,small volume,low weight,and excellent Low Probability of Intercept(LPI),LFMCW radar has found wide applications.Target echo signal of LFMCW radar is fisrt analyzed with beat-spectrum analysis-MTD stimulation,then the phase information is obtained from target echo signal,hence the distance and speed of the target.The method can largely reduce fixed clutters,and it is very effective in moving target detection. |
