Abstract

A passive system for the classification of isolated infrared signatures is briefly described. The hardware consists of magnifying optics,infrared filters and a beam splitter. The detector is a specially designed array consisting of two crosses 45° apart , with 8 or 16 pyroelectric detectors on each of the eight radial directions. The classification hardware consists in an analog parallel read-out and amplification,followed by a digital processor . The feature parameters by which the I.R. signature is classified into 6 alternative classes are : distributions of the detector outputs along each of the 8 radial directions,iso-radiation contours of the apparent picture of the source, and global I.R. emiss-on in two wavelength bands . Experimental as well as simulation results have been obtained .
