Abstract

The algorithm for the optimal signal processing in the Doppler speed and drift meter (DISS) was synthesized according to the specified mathematical model of the Doppler signal (in a form of stochastic differential equations) by the method of Markov theory of nonlinear filtering. The synthesized optimal algorithm of filtering allows to account a priori behavior of information and non-information parameters of Doppler signal more completely. The obtained algorithm is realized as a functional diagram of DISS filtering device. The analysis of the diagram shows that the obtained system is the tracking one for the Doppler frequency with the six signal processes filters and it provides the increase of the potential accuracy of the object speed measurement approximately by two times.
