The FGAN-FfO has participated in the U.S. Smoke Week XV which took place in May 1993 at Eglin AFB, Florida. The primary objective was to study the effect of smoke clouds of various types on some selected electro-optical sensors. Two different thermal imagers, operating in the wavelength bands 2 - 5 micrometers and 8 - 11 micrometers , and two different laser rangefinders, at wavelengths 1.54 micrometers and 10.59 micrometers , were involved. The imagers were aimed against both tactical targets and point sources over a distance of about 600 m. The laser rangefinders were fired during the tests at 4 s intervals over tactical ranges against a laser reflection target. System performance of these devices in the presence of smokes was measured and analyzed. By combining the data of one of the imagers with that of one of the rangefinders, the effects of smoke clouds on a potential fire control system were studied. Comparisons between the statistical results show significant differences for the various smoke events in degrading the performance of the systems involved. |
