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 identical irradiation parameters, and corresponding manipulation in a receiver. Estimations of measuring accuracy are shown. Proposed method application allows to increase self-descriptiveness of health monitoring systems for ionospheric radio communication lines by LFM signal.
