Precision Point Target Tracking

Chester L. Richards Jr.

Abstract:	Subresolution tracking may be achieved through a combination of proper imaging sensor design and algorithm selection. The requirement on the sensor for optimum performance is that images must be sampled by a stable grid which meets the Nyquist sampling criterion. For staring array sensors this requirement leads to a detector size and sample spacing which is quite different from the classical design choice. Once the focal plane has been properly designed, there is a selection of tracking algorithms which give approximately the same tracking performance. All of these algorithms show a residual single measurement error which is inversely proportional to the signal to noise ratio. The choice of a particular algorithm comes primarily from a trade between processing burden and clutter rejection. A system which is optimized for point target tracking will also be optimized, and will show improved performance, for extended target tracking and for pattern recognition.
