早在本世纪四十年代,随着超短波波段大功率(约10千瓦)发信机和高增益(40分贝以上)天线的出现,人们发现在几百公里远的距离上超短波信号仍能可靠地传输的现象.这时,接收信号的平均电平此按照电波绕射理论所估计的要大几十甚至几百分贝.随之1950年后,各国都进行了大量的传播试验和理论研究来探索超短波远距离传播的规律,发现这种传播是对流层散射传播;与此同时还拟制了利用这种传播的相应的对流层散射通信设备.目前,对流层散射通信已进入实际应用的阶段,许多国家已经建立了供军用或民用的对流层散射通信电路.
As early as the 1940s, with the emergence of high-power (about 10 kilowatts) ultra-shortwave transmitters and high gain (over 40 dB) antennas, it was found that ultra-shortwave signals could still reliably be at distances of hundreds of kilometers Transmission phenomenon .At this time, the average level of the received signal in accordance with the radio wave diffraction theory to estimate the large or dozens of hundreds of dB .After 1950, countries have conducted a large number of propagation experiments and theoretical studies to explore It is found that this propagation is the tropospheric scatter propagation and at the same time the corresponding tropospheric scatter communication equipment that exploits this propagation is also proposed.Currently, the tropospheric scatter communication has entered the practical application stage, and many countries have already Established for military or civilian tropospheric scattering communication circuit.
