| 摘 要： | 由于光电器件响应速率有限,在满足相同距离分辨率要求时,线性调频连续波（LFMCW）激光雷达需要较同体制微波雷达大得多的相对带宽,所以不能直接应用LFMCW微波雷达的距离与速度去耦合技术来提取目标距离和速度信息。针对LFMCW激光雷达中频信号的频谱特点,提出了利用均匀分段傅里叶变换的方法来解算目标的距离和速度信息。仿真实验表明,在中频信号信噪比较低的情况下,该方法具有较小的测距测速误差和较小的运算量,从而具有一定的实用性。 |
| 关 键 词： | 线性调频连续波 傅里叶变换 时宽带宽积 激光雷达 |

| Abstract: | Due to the corresponding rate limitations of the optoelectronic devices,LFMCW lidar's relative bandwidth must be larger than that of the microwave radars to meet the equivalent requirement of range resolution.Therefore,the theory suitable for LFMCW microwave radars cannot be applied directly to lidar to decouple the range information and velocity information of the moving targets.Based on the characteristics of the IF signal,this paper introduces a new method to decouple the range information and velocity i... |
