Title:
RADAR SYSTEMS AND METHODS USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2021/012970
Kind Code:
A1
Abstract:
System and method for determining a 3D coordinate of a moving target are provided. The system may obtain 2D detection data of the moving target generated by a 2D detection device including two detection assemblies that are mounted at a known height above a horizontal plane along a first axis that forms a tilting angle with the horizontal plane. The system may determine a 2D coordinate of the moving target in a first coordinate system including the first axis and a second axis that is perpendicular to the first axis based on the 2D detection data. The 2D coordinate of the moving target may include a first value of the first axis and a second value of the second axis. The system may determine the 3D coordinate of the moving target in a second coordinate system based on the 2D coordinate, the tilting angle, and the known height.
