Method and system for Doppler correction of Doppler detection and optical chirp distance detection

摘要

A technique for Doppler correction of chirp optical distance detection is based on a corresponding frequency difference between the return optical signal and a first chirp transmit optical signal having an up-chirp that increases in frequency over time. And obtaining a first set. A second set of distances is obtained based on a corresponding frequency difference between the returning optical signal and a second chirp transmitting optical signal having a down-chirp. A matrix of values for the cost function is determined, wherein each one-to-one value of the distance includes one distance in the first set and one distance in the second set. A pair of one distance in the matching first set and one corresponding distance in the second set is determined based on the matrix. The Doppler effect on distance is determined based on combining matching pairs of distances. The device is operated based on the Doppler effect. [Selection diagram] FIG.
