高频返回散射 meaning in Chinese

hf backscatter

The emphasis of this paper is to simulate the backscatter ionograms using ray tracing technology
本文研究的重点是利用数字射线追踪技术实现高频返回散射电离图仿真。
The ionosphere is a complex medium , which is aeolotropy , asymmetry , dispersive and changes randomly with time . in order to improve the communication quality of the shortwave that depends on the ionosphere , we should have aknowledge of the current condition of the ionosphere in real time . the backscatter sounding of high frequency can diagnose the real - time channel characters for shortwave communication or hf radar , which is great assistant to shortwave communication and hf radar
电离层是随机时变,各向异性,非均匀、色散的复杂介质。为了保证依赖于电离层进行的短波通信质量,必须了解电离层的实时状态信息。高频返回散射探测可以实时监测与短波通信或高频天波雷达相关的天波传播信道的状态,对短波通信和天波雷达工作起了重要的辅助作用。
