Abstract
A location detection system includes a first directional radar sensor, a second directional radar sensor and a controller. The first directional radar sensor has a first facing direction and a first radio coverage correspondingly, and is used to receive a first response signal upon detecting an object. The second directional radar sensor has a second facing direction and a second radio coverage correspondingly, the second radio coverage being partially overlapping with the first radio coverage, and is used to receive a second response signal upon detecting the object. The controller is used to determine which region the object is located in according to receptions of the first response signal and the second response signal.
