US 2025/0028036 A1 · POSITIONING METHOD AND MULTI-RADAR POSITIONING SYSTEM

Abstract

A positioning method and a multi-radar positioning system are provided. In the positioning method, a first object and a second object are detected by a first radar to obtain a first coordinate and a second coordinate on a first coordinate system respectively. The first object and the second object are detected by a second radar to obtain a third coordinate and a fourth coordinate on a second coordinate system respectively. A first candidate coordinate and a second candidate coordinate of the second radar on the first coordinate system are estimated according to the third coordinate and the fourth coordinate. The first candidate coordinate is selected from the first candidate coordinate and the second candidate coordinate as a first radar coordinate of the second radar according to the first coordinate and the second coordinate. The first radar coordinate is output.
