The technology of trajectory tracking of the targets by the emissions of their airborne radio transmitters, which uses the reflections from the arbitrarily-spaced random objects naturally occurring due to radiation of radio signals, has not yet gained widespread although it can be realized with the use of a single-position control system and can significantly improve the operating efficiency of a wide variety of systems and complexes of covert remote detection, tracking and control.

Conventionally, the problem of spatial localization of radio objects is solved by direction-finding or differential distance measurement methods, as well as their combination. In order to increase the convertness of operation, the methods for reducing the distance between the receiving centers and restricting the direction-finding base to one receiving position are studied. A single-position method for locating targets by the emissions of their airborne radio transmitters with the use of the transmitter’s direct radio signal and its copies reflected by random objects is studied. The basis of this method is the procedure for testing a hypothesis for the values of the spatial coordinates of reflectors which requires the availability of a priori information on the spatial coordinates of possible reflectors of radio signals in the area of the location of a single-position monitoring system. As a consequence, this method is difficult to implement in stationary and nonrealizable in mobile monitoring complexes, as it requires long-duration and labour-intensive operations to select possible reflectors of radio signals and measure their spatial coordinates prior to the start of the complex operation. In addition, this method does not provide the possibility of determining the velocity vector of the radio object which is evidence of its limited information content. In this paper we present a method of single-position determination of the coordinates and velocity vector of the radio objects based on the procedures for testing a hypothesis for the values of Doppler shifts of reflected signals and ensuring operation under conditions of a priori uncertainty of the form, sizes, reflective properties and spatial coordinates of reflectors.
