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.

[ What I claim is:] [1.] A spatio-temporal characteristic determination method of improved reliability comprising:the radiation of energy,the configuration of a portion of said radiation as at least one energy beam which is directed into an at least one dimensional array comprising at least two subapertures within an interrogation region, said interrogation region comprising the full extent in angular range, sometimes called a full field of view, within which said determination method operates,the placement of a substantial fraction of said radiation from at least one subaperture beam within the target aperture, which substantially intercepts a portion of a remote target in at least one axis throughout the majority of its operating range, wherein said axis is nominally perpendicular to the propagation direction of said beam,the maintainance of a portion of said radiation within the angular subtense of said target in a manner sufficient for spatio-temporal characteristic determination, andthe collection and analysis of the radiation returned from said target.
