METHOD FOR MEASURING DELAY OF PSEUDORANDOM PULSE TRAIN Russian patent published in 1994 - IPC

Abstract RU 2012147 C1

FIELD: radio engineering. SUBSTANCE: method involves generation of local reference signal and two local pseudorandom pulse trains which are shifted with respect to each other by interval which is same as pulse duration in train. Then two mutually correlated signals Tэ are generated by means of multiplication of received pulse train and local pulse trains. These signals are stored. Then local pulse trains are shifted in time. Time interval between starts of steps of local reference signal and local pseudorandom pulse trains is measured. Additional local pseudorandom pulse train is generated. It has delay R1 with respect to second local pseudorandom pulse train. Additional mutually correlated signal R1 is generated by multiplying received pseudorandom pulse train and third local pseudorandom pulse train. Signals R2, Tэ and additional signal R3 are compared. Their differences R1 and R2 are compared to given threshold V. Local pulse trains are shifted by R3 until R1-R2 and R3-R2 or until R2≅ R1. Values of mutually correlated signals R1-R2> V, R2≅ R3 and R3-R2> V are computed after each shift by Tэ. Correction to measured delay of pulse train is computed according to equation given in invention specification. Measured result of pulse train delay is corrected according to computed corrections R1, R2 and R3. EFFECT: increased precision.
