摘要
机载激光成像雷达在执行非合作目标识别/分类、精确成像制导、战场侦察和打击效果评估等方面有潜在的应用前景。在系统分析非相干探测激光雷达噪声特性的基础上,采用LOWTRAN7软件对激光雷达接收到的背景光功率进行了数值仿真。仿真结果表明,采用视场法、光谱分辨法和视频带宽法可以有效地抑制背景噪声,大幅度地提高激光雷达的探测距离,以满足机载火控系统对小目标远距离精确识别的作战使用要求。
The airborne laser imaging radar has potential application prospects in object identification/ classification ,precision imaging guidance, battlefield reconnaissance, and damage efficiency evaluation ect. In this paper, the noise characteristics of non-coherence detecting laser radar are systematically analyzed. LOWTRAN7 software is used in digital simulation of background radiation power received by the laser radar. The simulation result shows that： Field of View method, spectral resolution method and video bandwidth method can all suppress the background noise effectively, thus can greatly increase the detection range of laser radar. Therefore it can satisfy the operational requirement of airborne fire control system on precision identification of small targets at distant range.
