由于E_s突发电离层的散射传播,电视低频道易受到远台同、邻频干扰。本文先介绍E_s层的传播特性,再着重介绍抑制E_s层干扰波的天线技术。
Due to the scattering propagation of the E_s sudden ionosphere, the TV low-frequency channel is susceptible to interference with far-adjacent stations and adjacent channels. This paper first introduces the propagation characteristics of the E_s layer, and then focuses on the antenna technology to suppress the E_s interference wave.
