METHOD OF IMPROVING ACCURACY OF ESTIMATING DIFFERENCE IN TIME OF RECEPTION OF RADIO SIGNALS USING RADIO WAVE PROPAGATION CHANNEL FEATURES Russian patent published in 2014 - IPC G01S3/00 

FIELD: radio engineering, communication.

SUBSTANCE: method includes receiving a signal at two spaced-apart receiving centres, digitising voltage from the output of the antenna, detecting a signal at each receiving centre, estimating the difference in time of reception, which includes estimating the delay of the reflected signal relative to the forward signal at each receiving centre, estimating the difference in time of reception of reflected signals, calculating the difference in time of reception of forward signals as a sum of the delay between the forward and reflected signals at the first receiving centre and the delay between the reflected signals at the first and second receiving centres, minus the delay between the forward and reflected signals at the second receiving centre.

EFFECT: high accuracy of estimating the difference in time of reception of signals of a radio-frequency radiation source at two spaced-apart receiving centres.
