FIELD: radio engineering.
SUBSTANCE: invention refers to radar, radio navigation and can be used in radio engineering complexes, which determine the parameters of the aircraft movement based on the phase measurement method. Method for measuring the motion parameters in the phase radial systems is implemented by means of the device that consists of four receiving antennas, four signal amplifier-limiters, which are received by the antennas, two units of phase detectors, two ambiguity disclosure devices, the device for processing phase differences of received signals, the output device of measurement results, and consists in receiving the signal from the transmitter, which is located on board of the radiation object, for several pairs of receiving antennas, which are located at the ground receiving and recording point, in measuring the phase difference of the incoming signals for each pair of antennas, converting the measured phase differences into the line of position, which is a straight line, the intersection of which with the sphere of radius that is equal to the distance to the object of radiation, determines the current position of the radiation object, wherein the measured value of the phase difference of one pair of antennas is converted into the surface of position that is the hyperboloid of revolution with respect to the axis, which is formed by the line that connects the centers of one pair of antennas, the value of the phase difference of the other pair of antennas is converted into the rotation hyperboloid with respect to the axis, which is formed by the line that connects the centers of the other pair of antennas, the intersection of two hyperboloids of revolution is converted into the line of position of the radiation object in space, and the coordinates of the radiation object are defined as the intersection of this line of position with the sphere, which is determined from the results of measuring the distance to the radiation object.
EFFECT: achieved technical result is the preservation of the accuracy characteristics of the measurement of the motion parameters at any distances to the object, including, provided that the distance to the radiation object is commensurate to or less than the distance between the antennas of the exact scale.
