DESIGN OF INVERSE FILTER FOR PATTERN-RECOGNITION - ANALYSIS OF THE PERFORMANCE OF AN AMPLITUDE-COMPENSATED MATCHED-FILTER

The aim of this paper is to study the performance of an amplitude comp ensated matched filter as an optimization of the inverse filter. Analy sis by digital simulation of signal-to-noise ratio, discrimination and optical efficiency has been carried out using both binary and grey-le vel images in absence of noise. Subsequently, the scenes were immersed in real background. Amplitude compensated matched filter behaviour ha s been compared with matched filter, phase-only filter and inverse fil ter, showing its capabilities and limitations.
