高频信道是一种典型的时变信道,高频通信是军事移动通信的重要手段。由于数字通信、高频超视距雷达、遥测、遥感等新兴电子系统的出现和发展,使高频信道的实验测量和理论研究,一直为人们所重视。本文将扼要介绍作者近几年来在研究这一问题时所得到的若 High-frequency channel is a typical time-varying channel, high-frequency communication is an important means of military mobile communications. Due to the emergence and development of emerging electronic systems such as digital communications, high-frequency over-the-horizon radar, telemetry and remote sensing, experimental measurements and theoretical studies of high-frequency channels have been attracting attention. This article will outline what the author has learned from the study of this issue in recent years
