摘要
从理论上分析了蒸发波导的成因,并总结了其形成过程。概括了基于气象参数、雷达回波和激光探测预测蒸发波导方法的主要特征,通过对比分析,介绍了激光探测蒸发波导的基本原理和优点,并利用蒙特卡罗方法仿真了水汽压变化对气溶胶粒子的激光后向散射的影响,进一步验证了利用激光技术探测蒸发波导的可行性。
Abstract
The cause of evaporation duct is theoretically analyzed and its forming process is also summarized. The main characteristics of the evaporation duct motheds based on weather parameters, radar echo and laser detection are summarized. Through contrast analysis,the basic principles and advantages of laser detection evaporation duct are mainly introduced. The impact of the change of vapor pressure on the laser backscattering of aerosol particles is simulated by using the methods of monte carlo. The feasibility of using laser technique to detect evaporation duct is further verified.
