ABSTRACT:
An improved remote speed sensing technique is described which improves performance reliability by increasing the relative signal to noise ratio of a speed detector compared to that of a vehicle radar detector, by localizing at least one axis of the illuminating radiation to an angular region which is comparable to or within the subtence of the target vehicle, while minimizing illumination of a radar detector on the target vehicle.
