摘要
重叠因子是分析成像系统收发视场匹配的重要参数。介绍了选通型激光主动成像系统的工作原理,定性分析了系统成像性能与重叠因子的关系。将重叠因子引入了系统的分析设计中。从实际出发,分析计算重叠因子与系统发散角、视场角等参数的关系。结果表明利用重叠因子分析和设计系统发散角等参数的方法是可行的。
Overlap factor is important index to analyze imaging system view filed.the mechanism of range-gated laser active imaging system is introduced,and analyzed the relation between performance and overlap factor,and also introduced it into the system design.From the fact,the relation between overlap factor and system parameters is calculated by simulation.The calculation and analysis results indicate that using overlap factor to analyze and design system parameters is feasible.
