SYSTEMS AND METHODS FOR VEHICLE POSITION DETECTION

摘要

A system includes a transmission unit, a first reception antenna, a second reception antenna, and a processing unit. The transmission unit is configured to be disposed onboard a vehicle traversing a route, includes a transmission antenna, and is configured to transmit a location signal to a target disposed along the route as the vehicle traverses the route. The first reception antenna is configured to receive at least one reflection signal of the location signal reflected off the target. The second reception antenna is configured to receive the at least one reflection signal. The processing unit is configured to obtain first reception information from the first reception antenna and second reception information from the second reception antenna, perform a comparison of the first and second reception information, and determine a position of the vehicle using the comparison of the first and second reception information.

1. A system comprising:
a transmission unit configured to be disposed onboard a vehicle traversing a route, the transmission unit comprising a transmission antenna and configured to transmit, via the transmission antenna, a location signal to a target disposed along the route as the vehicle traverses the route; a first reception antenna configured to receive at least one reflection signal of the location signal reflected off the target; a second reception antenna configured to receive the at least one reflection signal reflected off the target; and a processing unit operably connected to the first reception antenna and the second reception antenna and configured to:
obtain first reception information from the first reception antenna and second reception information from the second reception antenna;perform a comparison of the first and second reception information; anddetermine a position of at least one of the vehicle or the target using the comparison of the first and second reception information.
