1. A radar system suitable for use on a vehicle, said system comprising:
a first radar sensor configured to output a first signal indicative of a first target in a first area proximate to a vehicle;
a second radar sensor configured to output a second signal indicative of a second target and a reflection surface in a second area proximate to the vehicle and different from the first area, wherein the reflection surface is characterized as being closer to the second radar sensor than the second target; and
a controller that receives the first signal and the second signal, wherein the controller is configured to determine that the second target is a reflection of the first target when a reflection-line that bisects and extends orthogonally from a line-segment extending between the first target and the second target intersects with the reflection surface detected by the second sensor.
