为了满足探测的目的,有效获取和反演雷达数据,需要对激光雷达系统的参数进行设计。给出了激光大气雷达系统中重合系数(几何因子)的计算方法,并且结合我校现有的激光大气雷达系统的技术参数,从对0～3km的气溶胶后向散射回波的有效探测出发,讨论了系统参数对重合系数的影响和利用改变系统参数的方法改变重合系数,以实现对激光雷达系统优化设计的可行性。计算和分析表明,该方法简单、直观、有效。
In order to meet the purpose of detection, the effective acquisition and inversion of radar data requires the design of the parameters of the laser radar system. The calculation method of coincidence coefficient (geometric factor) in laser atmospheric radar system is given. Based on the technical parameters of the existing laser atmospheric radar system in our university, from the effective detection of 0 ~ 3km aerosol backscattering echo , Discussed the impact of system parameters on the coincidence coefficient and changed the coincidence coefficient by changing the system parameters in order to realize the optimal design of laser radar system. The calculation and analysis show that the method is simple, intuitive and effective.
