Abstract. The operations of the method of passive one-position angular-difference-Doppler location providing a measurement of the coordinates and trajectories of the motion of radio-emitting objects equipped with radio transmitting devices of modulated signals with phase, frequency-phase and/or quadrature amplitude modulation of various multiplicity are justified for the case of their uniform, rectilinear displacement on a constant height. First, the values ​​of the heading angles of the direction of motion of objects are determined on the base of measurements at equidistant intervals of time of the angular coordinates and the reconstructed carrier frequency of the modulated signals. Then, the magnitude of the velocity vector of the object, the path traversed in a fixed time and åđó location of objects as points of intersection of position lines - rays drawn from the origin to the corresponding azimuth angles and a circle passing through the origin of coordinates, the chord of which is the above-mentioned segment of the path, are calculated using the dependence of the magnitude of the Doppler carrier frequency increment on the direction of motion.  In the following sections, in accordance with the operations of the inverse-kinematic angular-difference-Doppler method, the structure of a passive single-position radar station including two groups of devices is synthesized:

- observation channels with devices for primary processing;

- multiprocessor secondary processing device.

Also, an estimation of the accuracy characteristics of the system was made, which confirmed the possibility of its use for measuring the range, speed and direction of movement of objects.

Key words: passive one-position angular-difference-Doppler location, radar system, radio-emitting object.
