Abstract
A detecting device for detecting moving target vehicles from a moving host vehicle, comprising a first detector means mounted to the host vehicle and aligned to a stationary target area for generating at least a first output representative of the stationary target area at least at a time T, a second detector means mounted to the host vehicle and aligned to the stationary target area for generating at least a second output representative of the stationary target area at least at a time T, and a control system to receive the first and second outputs and to compare the first output at Tto the second output at Tto identify any differences between the outputs, whereby a target vehicle moving in the stationary target area may be detected.
