Abstract: Embodiments are provided herein for a radar system and a method for determining true velocity, which includes: obtaining a first radial velocity component that corresponds to a target object, based on sensor data detected by a first radar sensor on a vehicle; obtaining a second radial velocity component that corresponds to the target object, based on sensor data detected by a second radar sensor on the vehicle; and calculating a true velocity vector of the target object based on a trigonometric relationship established between the first radial velocity component and the second radial velocity component.
