Measure of frequency dependences of Doppler frequency shift and spread time of each ionospheric mode with help of continuous LFM signal
It is considered a method for definition of frequency dependences of group delay time and Doppler frequency shift of short wave propagation separate modes, based on radiosignal probing by means of two continuous linearly frequency modulated signals, which are shifted on time period T , with identica...
