METHOD OF SIGNAL RECIPROCAL DELAY MEASUREMENT WITH PROGRAM OPERATING FREQUENCY TUNING (POFT) Russian patent published in 2008 - IPC G01S1/00 

FIELD: physics.

SUBSTANCE: substance of method of signal reciprocal delay measurement with program omnirange operating frequency tuning implies application of stage-by-stage reciprocal signal phase spectrum reconstruction, except that within address signal set at the first stage, and detection of delay time based thereof. At the second stage reciprocal signal phase spectrum is reconstructed within frequency range 0÷f_n, where f_n is width of address signal set. At the third stage disambiguation of two previously reconstructed reciprocal phase spectrum is provided alongside with calculation of reciprocal signal delay with margin error inversely proportional to radio signal carrier frequency value.

EFFECT: higher measurement accuracy of reciprocal signal delay.
