METHOD OF LOCATING NAVIGATION OBJECT Russian patent published in 2016 - IPC G01S13/00 

FIELD: radar and navigation.

SUBSTANCE: invention may be used in navigation systems and local area networks to control the movement of mobile objects in local zones navigation. This result is achieved due to the fact that the method is based on the emission object navigation high harmonic signal taking it into several reference navigation points with known coordinates, wherein with the object navigation additionally emit second high harmonic signal having a frequency different from the frequency of the first high-frequency harmonic signal by a predetermined amount in each of the reference navigation points receive this signal along with the first, is formed from the received signals, signals of the difference frequency, transmits the generated signals to a central processing station, where from each further generating signal scale frequency, the magnitude of which is n times smaller difference frequency is measured and fixed phase difference signal of the difference frequency, received from various control points, and the phase difference formed from these signals scale frequency, at the end of the measurement results of measurements of phase differences converted into coordinates of the object navigation based on the mutual arrangement of the central point of the processing and the reference navigation points.

EFFECT: increase noise immunity, improve the accuracy of determining the coordinates of the object navigation.
