摘要

电离层等离子体或核聚变的不规则性往往具有不同的尺度，因此难以计算探测无线电信号的特征。双加权傅立叶变换(DWFT)方法描述了菲涅耳衍射效应典型的小尺度不规则，以及随机焦散的影响与聚焦透镜样不规则。本文介绍了用DWFT方法研究多尺度随机非均匀等离子体中波的统计特性的最新结果。

Statistical Characteristics of a Radiowave Propagating in a Multiscale Randomly Inhomogeneous Plasma

Irregularities of ionospheric plasma or nuclear fusion quite often have different scales, thereby making it difficult to calculate characteristics of a sounding radio signal. The Double Weighted Fourier Transform (DWFT) method describes Fresnel diffraction effects typical for small-scale irregularities as well as effects of random caustics associated with focusing on lens-like irregularities. This report presents the recent results of studies of statistical characteristics of waves in a multiscale randomly inhomogeneous plasma by the DWFT method.
