A system, comprising: at least one detector configured to detect a signal from at least one source and provide first signal information regarding a distance a detected signal traveled between the at least one source and the at least one detector, wherein the at least one detector is associated with a vehicle; and a processor that is configured to determine whether the first signal information corresponds to a direct signal path between the at least one detector and the at least one source or the first signal information corresponds to a reflected signal (34, 38) based on second signal information from at least one other detector, wherein the at least one other detector is movable relative to the vehicle, and determine a location of the at least one detector based on the first signal information when the first signal information corresponds to the direct signal path between the at least one detector and the at least one source, characterized by the processor being further configured to determine a position of the at least one other detector relative to the vehicle; determine a position of the vehicle relative to the at least one source; determine whether at least one portion of the vehicle obstructs a direct signal path between the at least one source and the at least one other detector based on the determined positions; and determine that the at least one other detector does not have a direct signal path between the at least one other detector and the at least one source and that the second signal information corresponds to a reflected signal (34, 44) between the at least one source and the at least one other detector when the at least one portion of the vehicle obstructs the direct signal path. at least one detector configured to detect a signal from at least one source and provide first signal information regarding a distance a detected signal traveled between the at least one source and the at least one detector, wherein the at least one detector is associated with a vehicle; and a processor that is configured to determine whether the first signal information corresponds to a direct signal path between the at least one detector and the at least one source or the first signal information corresponds to a reflected signal (34, 38) based on second signal information from at least one other detector, wherein the at least one other detector is movable relative to the vehicle, and determine a location of the at least one detector based on the first signal information when the first signal information corresponds to the direct signal path between the at least one detector and the at least one source, determine whether the first signal information corresponds to a direct signal path between the at least one detector and the at least one source or the first signal information corresponds to a reflected signal (34, 38) based on second signal information from at least one other detector, wherein the at least one other detector is movable relative to the vehicle, and determine a location of the at least one detector based on the first signal information when the first signal information corresponds to the direct signal path between the at least one detector and the at least one source, characterized by the processor being further configured to determine a position of the at least one other detector relative to the vehicle; determine a position of the vehicle relative to the at least one source; determine whether at least one portion of the vehicle obstructs a direct signal path between the at least one source and the at least one other detector based on the determined positions; and determine that the at least one other detector does not have a direct signal path between the at least one other detector and the at least one source and that the second signal information corresponds to a reflected signal (34, 44) between the at least one source and the at least one other detector when the at least one portion of the vehicle obstructs the direct signal path. determine a position of the at least one other detector relative to the vehicle; determine a position of the vehicle relative to the at least one source; determine whether at least one portion of the vehicle obstructs a direct signal path between the at least one source and the at least one other detector based on the determined positions; and determine that the at least one other detector does not have a direct signal path between the at least one other detector and the at least one source and that the second signal information corresponds to a reflected signal (34, 44) between the at least one source and the at least one other detector when the at least one portion of the vehicle obstructs the direct signal path.
