Abstract

The paper considers the problem of estimating the vector of signal parameters in a large a priori domain in the presence of fluctuation noise and Bernoulli’s flow of pulses. It is suggested to include, in the algorithm of processing of received signals, a median filter to weaken the pulse flow. The correlation matrix of estimation of the unknown vectorial parameter of signal and the probability of reliable estimation of this parameter are found, with the results of statistical simulation included.
