高空核爆附加电离层对短波通信链路影响的模拟
Simulation of Effects of High-Altitude Nuclear Explosion on High-Frequency Communication Link
摘要
Abstract
To investigate the effect of such explosions on high-frequency(HF)communication systems,the paper employs a two-dimensional ray-tracing method to simulate HF communication links between transmitters and receivers near the explosion area.Then,the absorption loss and Doppler shift of HF communication signals on the different distances are estimated.Firstly,the IRI-2016 ionospheric model is integrated with additional ionospheric layers under different conditions to construct the ionospheric background.Then,HF communication links with different distances between the transmitter and receiver are constructed,and the corresponding ionospheric absorption and Doppler shift of HF signal are calculated to obtain the propagation characteristics of the signals in the additional ionosphere on the HF communication links.Finally,the characteristics of HF communication signal are further analyzed and discussed with different communication distances.Simulation results show that the effects of the additional ionization region on HF communication are complex,depending on the communication distance,communication frequency,transmitter-receiver distance,etc.When the HF communication link passes through the additional ionization core region,which makes the absorption order of signal reach about 103 dB and the Doppler shift can reach about 102 Hz.关键词
