<title>Detection of targets in terrain clutter by using multispectral infrared image processing</title>

Abstract: SUMMARY PROBLEMInvestigate a weighted-difference signal-processing algorithm for detecting ground targetr by using dual-band IR data. RESULTSThree variations of the algorithm were evaluated: (1) simple difference; (2) minimum noise; and (3) maximum SNR. The theoretical performance was compared to measured performance for two scenes collected by the NASA TIMS sensor over a rural area near Adelaide, Australia, and over a wooded area near the Redstone Arsenal. The theoretical and measured results agreed extremely… Show more

“…But the performance highly depends on SNR. Hoff etc [4] use 2D LMS adaptive scheme to distinguish between targets and clutter. According to infrared IT{ II\Ii IT{Fl) multi-spectral characteristic information of targets, background and decoys, Wu etc [6] present an automatic target recognition algorithm by fusing target information of space and spectrum.…”

“…The difference of spectral radiation and reflection characteristics in diverse wavebands between background and real target can be generalized as [1][2][3][4] : 1) the radiation of natural background and some targets can be approximated by greybody radiation, and the target's multispectral image in adjacent sub-band is highly correlated; 2) The radiation of decoy is selective, the distribution of radiant intensity in different sub-band is distinctive and correlation is low [5] . Hence, an automatic target recognition algorithm based on statistical dispersion of infrared multispectral images(SDOIMI) is proposed here.…”
