Method, device and system for antenna delay calibration
The present invention relates to positioning technology and more particularly, to a method, device and system for antenna delay calibration. An embodiment of the present invention provides a method for antenna delay calibration, including the following steps: receiving delay and location distance between a first node and a second node; inputting the delay between the first node and the second node into a preset detection distance calculation formula to obtain a detection distance between the first node and the second node; inputting the location distance and detection distance into a preset actual delay calculation formula to obtain an actual delay; and inputting the actual delay into a node to calibrate and verify the node. The embodiment of the present invention obtains the actual delay by calculating the location distance and detection distance. Compared with dedicated equipment, each node is measured and calibrated, the implementation cost is low, it is convenient and fast, and the applicability is high, and batch measurements are realized as well.
