空間環(huán)境對無線電波傳播的影響綜述

The influence of space environments on radio propagation

摘要: 文章研究了空間環(huán)境對無線電通信的影響，主要體現(xiàn)在多種因素制約下的等離子體環(huán)境對電波傳播的影響,。首先介紹了幾種典型的電離層模型,，接著詳細(xì)講述了工程實(shí)用電離層模型；隨后給出了電磁波在等離子體環(huán)境中的傳播路徑和等離子體介質(zhì)在磁場環(huán)境下對電磁波影響的定量分析,，并建議將空間等離子體環(huán)境（包括星際等離子體環(huán)境和電離層等離子體環(huán)境等）作為一個整體進(jìn)行研究,，來考慮地磁場對等離子體電磁特性的影響；最后基于目前理論的不足與實(shí)際需求的矛盾,，探討未來的研究方向,。

Abstract: In this paper, we investigate the impacts of the space environment on radio propagation, especially that of the plasma environment. Several typical models of the ionosphere are discussed, focusing on models commonly used in engineering. A quantitative analysis of the influence of ionosphere on radio propagation and path characteristics is then made. An integral model of the space plasma environment (including interplanetary plasma environment and ionospheric plasma environment)is proposed for studies on electromagnetic impacts of the Earth’s magnetic field. Finally, the future research directions on the impacts of space environment on communication are suggested.
