Scientific paper
This paper describes the application of matched filter theory and maximum likelihood estimation to point source target position estimation in a scanning electro-optical system. The estimation is maximum likelihood at every pixel regardless of the noise and responsivity characteristics across the detector array. Algorithms are detailed and hardware is presented which is well matched to the implementation of the algorithms. Software issues are also described. The hardware is composed of a data flow processor and a general purpose signal processor, both manufactured by Signal Processing Systems, Inc.
