METHOD OF MEASURING DISPLACEMENT PARAMETERS OF PROBING SIGNAL SOURCE Russian patent published in 2013 - IPC G01S3/00 

FIELD: radio engineering, communication.

SUBSTANCE: method involves successively measuring time intervals between reception of a plurality of probing signals, calculating the difference between intervals of neighbouring pairs of measurements, determining distance travelled by a moving sonar between neighbouring radiations as a product of the difference between intervals and the speed of sound, determining the average interval between two consecutive probing signals, the average interval between three probing signals, the average interval between four probing signals and the average time between the average intervals, then determining radial speed of the moving sonar, and in order to determine radiation distance of the last probing signal, the difference between the time of receiving the last signal and the time of receiving the previous signal is determined; the difference is then used to calculate the time interval between probing signals and the last difference is multiplied by the speed of sound.

EFFECT: measurement of the speed of a mobile carrier and distance thereto.
