利用非相关散射雷达可以在不同经纬度记录到电离层F层中P_(c3_5)型磁脉动。这些脉动的分析需要对信号过程采用先进技术进行。本文介绍利用维纳滤波器方法对电离层离子速度及地面磁脉动H分量进行一对一分析,从中抽取出其相关部份,从而实现对被噪声“污染”的信号过程进行估值和滤波。 P_ (c3_5) -type magnetic pulsations in the ionosphere F-layer can be recorded at different latitudes and longitudes using non-correlated scatter radar. The analysis of these pulsations needs to be done using advanced techniques for the signal process. In this paper, one-to-one analysis of the ionospheric ion velocity and the ground magnetic pulsation H component using the Wiener filter method is introduced, and the relevant parts are extracted therefrom so as to estimate the signal process contaminated by noise and pollution Filter.
