利用 CCD作为探测接收装置的激光主动探测系统，其突出优势是可以获得直观的 “猫眼”目标视觉效果。通过“猫眼”目标与漫反射目标的回波功率比模型，讨论了激光主动探测的 “猫眼”效应原理。对基于 CCD的激光主动探测系统的关键硬件组成以及系统工作波长的匹配问题进行了分析，在外场 300 m及 2 500 m距离上进行了典型 “猫眼”目标的探测实验。实验结果表明，在一定探测距离上，该激光主动探测系统可将典型 “猫眼”目标从背景中清晰检出，从而验证了该激光主动探测系统的有效性。

The most distinguished advantage of an active laser detection system based on CCD detection device is the capability of acquiring the straightforward vision of “cat-eye” targets. The active laser detection theory based on “cat-eye” effect was discussed according to the model for echo power ratio of “cat-eye” target and diffuse reflection target. The key components of this detection system were described and the wavelength matching problem of CCD device and laser source was analyzed. The detection experiments were made by using typical “cat-eye” target at different distances, such as 300 m and 2 500 m. The experimental result shows that the “cat-eye” target can be easily found from background at a certain detection distance, so the validity of the active laser detection system is proved.
