Multiple target distance measurement method based on phase measurement principle

摘要

Sampled value was formed and because it retains optionally, the periodic signal (7) time dispersion emission and sampling of the reception signal were used, the object (2a and 2b) to distance is decided simultaneously in the range measurement method due to phase measurement principle, with that and the signal is reflected the object (2a and 2b) by piles up and possesses the signal part which it can be brought together. As for the statistical parameter approximate problem which is based on the mathematical signal model, the object of one or more (2a and 2b) the set point for (2a and 2b) number to be pre-set, or fundamentally the number of objects be decided by the above-mentioned method, inequality Several 1 With Several 2 It is solved by being formed.The distance which is pre-set Several 3 With Several 4 Here Several 5 Is set to the measuring range of the Distance Measuring Equipment.
