Abstract. This paper is devoted to modern approaches to development of new positioning algorithms which will guarantee the achievement of the minimum mean square error and do not create excessive computing load. The algorithm performing the search of global extremum in problems of source position estimation using one-step methods based on a likelihood function for two types of passive radar systems was proposed. The first system is a passive radar system consisting of narrow-base subsystems; the second system is the combined passive radar system which includes several narrow-base subsystems together with a wide-base passive radar system.

According to results of computer simulation, the analysis of the frequency of appearing abnormal errors and relative time spent on calculations was made. The comparison performed using the proposed algorithm with an adaptive step and a universal method of global extremum searching, that is “particle swarm”, showed that the developed algorithm requires up to 20 times less computational costs and vanishes abnormal errors.

Key words: digital signal processing, passive radar system, global maximum searching, one-stage estimation algorithm.
