POSITION DETECTION SYSTEM, METHOD THEREFOR, AND COMPUTER-READABLE MEDIUM

摘要

A position detection system, including a memory storing instructions, and at least one processor configured to process the instructions to receive measured waveform signals sent out from an object to be measured via a first sensor and a second sensor, receive the broadcasting radio wave signals sent out from the first sensor and the second sensor, separate the measured waveform signals and the broadcasting radio wave, for each sensor, estimate an offset between the sampling frequencies of the measured waveform signal of the first sensor and the measured waveform signal of the second sensor based on the broadcasting radio wave signals respectively sent out from the first sensor and the second sensor, correct the measured waveform signal sent out from the second sensor based on the estimated offset between the sampling frequencies, and detect a position of the object to be measured based on the measured waveform signal sent out from the first sensor and a signal obtained by correcting the measured waveform signal sent out from the second sensor.
