Multifrequency phase method for measuring the radial velocity of targets

Abstract . The article deals with the development of a multifrequency phase method for measuring the range and radial velocity of targets. It is shown that to measure the distances of targets it is necessary to measure the amplitude and phase characteristics by envelope of the spectrum of the probing signal, and to measure the radial velocity - the measurement of the Doppler shift of the spectral components at the intermediate frequency.
