| 摘 要： | 分析了出瞳扫描方式扫描视场角与激光雷达光学系统参数的关系，认为最大扫描视场角比主天线望远镜静态视场角小，在信号过程线性的前提下，根据强度像的瑞利判据提出了扫描激光雷达角分辨率公式建议。对主要结论都进行了实验验证。

| Abstract: | The field-of-view of a scanning laser radar which adopts a pre-objective beam steering optical antenna is discussed - It shows that the scanning field-of-view is usually smaller than the defined field-of-view of the antenna telescope. The resolution of a scan-ning radar is also ana]ysed for the TEM00 Gaussian probe beam case. The judgements are suggested for direct and coherent detection according to the well-known Rayleigh criteri-on for human vision. Al1 conclusion are supported by our experiments. |
