摘要
利用推广的惠更斯—菲涅尔原理,考虑了大气湍流对激光从发射机到目标和从目标到接收机两条路径的影响,研究了大气湍流中目标散射问题,并以漫射目标为例进行了具体分析,讨论了大气湍流对散射场的互相关函数、平均强度、强度协方差及强度方差等的影响。
The extended Huygens—Fresnel principle has been used to analyse the backscattering of a target in the atmospheric turbulence.The treatment includes the effects of the atmospheric turbulence both on the laser beam as it propagates to the target and on the scattered field as it propagates back to the receiver.For a diffuse target,the effects of the turbulence on the mutual coherence function,mean intensity, covariance and variance of the scattered field are studied in detail.
