摘要 解析形式的相位函数是进行水下光传输仿真研究的一个重要特性参数,以Petzold平均粒子相位函数作为标准,比较了OTHG相位函数、Haltrin相位函数和Founier-Forland(FF)相位函数解析模型的准确性,结果表明:FF相位函数最好,Haltrin相位函数其次,OTHG相位函数最差。针对如何选择FF相位函数存在(n,μ)的问题,阐述了2种(n,μ)的选择方法并进行了比较,比较结果表明Freda方法是目前为止所发现的一种较好的选择方法。 The analytical formal phase function is an important parameter for the simulation research on underwater imaging system. Henyey-Greenstein (0THG)phase function, Haltrin phase function and Fournier-Forland(FF) phase function are compared by taking the Petzold phase function as standard. The result shows that FF phase function is the best, Haltrin phase function is better, and OTHG phase function is the worst. The value of (n,/x) must be considered while using FF phase function. Two methods of the choice of (n,/x) are compared, and the result shows that Freda's method is the best method until now
