Location detection system

A location detection system, comprising:

• a first directional radar sensor having a first facing direction and a first radio coverage correspondingly, and configured to receive a first response signal upon detecting an object;
• a second directional radar sensor having a second facing direction and a second radio coverage correspondingly, and configured to receive a second response signal upon detecting the object, the second radio coverage being partially overlapping with the first radio coverage;
• and
• a controller configured to determine which region the object is located in according to receptions of the first response signal and/or the second response signal, wherein
• the region is selected from at least one overlapping region and at least two non-overlapping regions, and the at least one overlapping region comprises an overlapping area formed by the first radio coverage and the second radio coverage, and wherein
• the controller determines that the object is located in one of the at least two non-overlapping regions when receiving the first response signal but not the second response signal, or when receiving the second response signal but not the first response signal.
