Title:
ANTENNA DELAY CALIBRATION METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/006780
Kind Code:
A1
Abstract:
The present invention relates to the field of positioning, and in particular to an antenna delay calibration method, device and system. The antenna delay calibration method provided by an embodiment of the present invention comprises: receiving the delay and the location distance between a first node and a second node; calculating according to the delay between the first node and the second node to obtain the detection distance between the first node and the second node; calculating according to the location distance and the detection distance to obtain actual delay; and performing antenna delay calibration or verification on the obtained actual delay. According to the embodiment of this solution, the actual delay is obtained by calculating the location distance and the detection distance. Compared to a method using professional apparatuses to measure and correct each node separately, this method has low implementation cost and high applicability and is convenient and easy to operate. Batch measurement can be performed by means of the present invention.
