Long-distance propagation effects in the HF signals from different heating facilities observed with using passive Doppler sounding equipment at Irkutsk

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
We present the first observation results of long-distance propagation effects of short radio waves at pump frequency, observed by passive Doppler sounding equipment at Irkutsk during heating facilities operation. We demonstrate two effects: dependence of the received signal amplitude on the propagation path during power-stepping mode and difference ...

On the detection of acoustic‐gravity waves generated by typhoon by use of real time HF Doppler frequency shift sounding system

Radio Science, 1985
A development of a direct vision type high‐frequency Doppler frequency sounder and a setup of HF Doppler frequency sounding array at the northern part of Taiwan Island were presented. By use of all typhoons that occurred in 1982 and 1983, the detectability of the typhoon‐generated acoustic‐gravity waves by use of this HF Doppler frequency sounding ...
