SYSTEMS AND METHODS FOR VEHICLE POSITION DETECTION
First Claim
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; and
determine a position of at least one of the vehicle or the target using the comparison of the first and second reception information.

Abstract
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.

9. A method comprising:
-
transmitting, from a transmission unit comprising a transmission antenna disposed onboard a vehicle, a location signal to a target disposed along a route as the vehicle traverses the route; receiving, at a first reception antenna disposed onboard the vehicle, at least one reflection signal of the location signal reflected off the target; receiving, at a second reception antenna disposed onboard the vehicle, the at least one reflection signal reflected off the target; comparing first reception information from the first reception antenna and second reception information from the second reception antenna; and determining a position of at least one of the vehicle or the target using the comparison of the first and second reception information. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A tangible and non-transitory computer readable medium comprising one or more computer software modules configured to direct one or more processors to:
-
transmit, from a transmission unit comprising a transmission antenna disposed onboard a vehicle traversing the route, a location signal to a target disposed along the route as the vehicle traverses the route; compare first reception information from a first reception antenna and second reception information from the second reception antenna, wherein the first reception information corresponds to at least one reflection signal of the location signal reflected off the target received by the first reception antenna, and wherein the second reception information corresponds to the at least one reflection signal of the location signal reflected off the target received by the second reception antenna; and determine a position of at least one of the vehicle or the target using the comparison of the first reception information and the second reception information. - View Dependent Claims (18, 19, 20)
