摘要
针对空间目标探测，介绍了激光主动成像系统的组成，详细分析了空间目标及背景的辐射特性；根据成像分辨率、调制对比度、最小可探测功率、系统信噪比等参数，分别给出作用距离模型，并对激光主动成像系统性能进行分析和仿真计算；仿真结果表明：利用激光主动成像探测系统可对一定距离的空间目标进行成像探测。
In order to detect spatial object effectively, the structure of laser active imaging system is described, and the radiation characteristic of spatial object and space circumstance is analyzed in detail. The paper analyzes the performance of laser active imaging system by giving a model of operation range based on the resolving power, the modulation contrast ratio, the minimal detectable laser power, and the signal-to-noise ratio of the system respectively. The simulation calculation for system performance is carried on. The result indicates that the spatial object within some distances can be imaged with this system.
