Abstract
A method and apparatus for determining a distance between a first radar system disposed on a vehicle and a second radar system disposed on the vehicle. A target reflector is moved along a track to a location along a perpendicular bisector of a baseline connecting the first radar system and the second radar system. A direct range measurement is obtained for at least one of the first radar system and the second radar system, and a bistatic range measurement is obtained between the first radar system and the second radar system. A processor determines the distance between the first radar system and the second radar system using the direct range measurement, the bistatic range measurement and a radial length of the target reflector.
