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。
Airborne laser imaging radars have potential applications in the implementation of non-cooperative target identification / classification, precise imaging guidance, battlefield reconnaissance and combat effectiveness assessment. Based on the systematic analysis of noise characteristics of incoherent detection laser radar, the LOWTRAN7 software was used to simulate the background optical power received by lidar. Simulation results show that the use of field of view, spectral resolution and video bandwidth method can effectively suppress the background noise, greatly improve the detection range of lidar in order to meet the airborne fire control system for small targets accurately identify the use of long-range combat Claim.
