Embodiments of the present invention provide monitoring apparatus for monitoring a target object external to a vehicle. The apparatus is operable to determine whether the target object is a valid target object in dependence on a value of a maximum range Rmax from the vehicle at which the target object has been detected. The apparatus may be operable to pre-arm a braking system and optionally apply a braking system responsive to a determination that a risk of collision exists. |
