摘　　要：通过对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，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，还提出了一些需要进一步深入研究的关键问题．Based on the analysis and processing of the test data obtained from the airborne underwater target detection by lidar in China and with Monte Carlo simulation, the effects of the effective attenuation coefficient, atmosphere conditions, wind speed, seawater turbidity, sloping of the underwater target on the airborne oceanic lidar system are studied. Some new approximate estimating formulae and curves suitable for engineering design purposes are derived. The abnormal phenomena during the test are explained and key problems for further study are suggested.
