PHASE-DIFFERENCE RADIO NAVIGATION SYSTEM WITH BROADBAND SIGNAL Russian patent published in 2016 - IPC G01S5/00 G08G1/123 G01S3/46 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to radio navigation and can be used in local navigation systems and networks for controlling movement of mobile objects in local navigation areas. Said result is achieved due to that system comprises, installed on navigation object, reference quartz generator, two frequency synthesizers, adder, first frequency divider, pseudorandom pulse sequence generator, high-frequency signal transmitter, consisting of a phase modulator and amplifier, arranged at reference points with known coordinates three receivers of signals emitted from navigation object, three measurement channels (differential frequency forming channels), each comprising series-connected balance mixer, narrow-band filter, limiting amplifier, resonance amplifier, arranged in central processing station second, third and fourth frequency dividers, six phase detectors, six analogue-to-digital converters, navigation object coordinate computer. Listed components are connected to each other in a certain manner.

EFFECT: wider region in space, within which is possible unambiguous determination of coordinates of navigation object with given accuracy, high noise-immunity of system.
