Abstract

The article deals with the estimation of the radial velocity when using a coherent burst of radio pulses as applied to the presence of correlated fluctuations of the initial phases in the radio pulses reflected from the target. The accuracy of the measurement of the burst frequency  is evaluated  for case of coordinated processing without taking into account the phase fluctuations.  The signals at the input of the radar’s receiver is an additive mixture of signals reflected from the targets, and uncorrelated Gaussian noise, that is the assumption of investigating.  It is assumed, that the phase fluctuations of the received radio pulses bursts are distributed according to normal probability laws with zero mean, and correlations of phase fluctuations decrease with exponential or alternating, sign-variable laws by increasing interval between radio pulses within the bursts.  This analysis makes it possible to determine the conditions under which the complication of the processing algorithm for this radar signal is considered justified.
