The possibility of phase measurements of Doppler frequency
Abstract
The present work gives a probabilistic analysis of a scheme for using phase measurements in a multichannel receiver in order to determine the Doppler frequency of a signal reflected from moving objects. A method of estimating Doppler frequency is set forth for the case of a small number of complex pulses arriving at the input of the receiving system. The rms error in estimates of Doppler frequency is determined as a function of noise parameters at the input of the phase-measuring device. The block scheme of a phasometric system is presented with which the practical potential accuracy of Doppler frequency measurements can be obtained.
