One-stage estimation of the location of a radio source by a passive system

The problems of analysis and implementation of the algorithm of one-stage estimation of the radiator location are considered. The method of calculating the covariance error matrix for the one-stage algorithm is proposed. The comparative analysis of one- and two-stage algorithms is performed. It is shown that they have equal accuracy when the signal-to-noise ratio is above a certain threshold value. The advantage in the estimation accuracy of the one-stage algorithm in comparison with the two-stage algorithm is revealed at low values of the signal-to-noise ratio, when abnormal errors of measurements take place.
