Exploration of azimuth estimation algorithms in radio systems of short-range navigation

In this paper the actual tasks of estimation azimuth in radio systems of short-range navigation (RSSRN) are presented. For example, these tasks are used in airplane landing systems. The estimation azimuth algorithms, that uses rejection of the passive interferences, are provides higher accuracy than algorithms without rejection. But the relation a signal/noise is decrease, therefore the signal energy must be increased. The estimation of maximal probability with using rejection of the passive interferences provides the best accuracy.
