摘　　要：通过对我国首次机载激光水下目标探测试验数据的分析和处理，并辅之以必要的蒙特卡罗模拟实验，就有效衰减系数、大气、风速、海水分层、目标倾斜等因素对雷达系统性能的影响进行了研究，首次总结出适合工程设计使用的近似估算公式和曲线，阐述了试验中出现的异常现象，并给出了合理的解释，最后还提出了一些需要进一步深入研究的关键问题．Based on the first airbome underwater targets detection test in China and Monte Carlo simulation, me key factors to the airberne oceanic lidar system, which include effective attenuation coefficient,atmosphere, speed of wind, turbidity layer, sloping of the undempter target, are studied. Some new approximation estimation formulation and curves which are suitabIe for engineering design are firstly derived. The abnormal phenomena in the test are explained. The problems needed to pay nrore attention to are also put forward.
