On the Military Utility of Spectral Design in Signature Management : a Systems Approach

Abstract: There is an ongoing duel between military sensor development and developments in signature management. The last decade, with warfare characterized by joint expeditionary operations and asymmetry, h ...

Spectral simulation and method design of camouflage textiles for concealment of hyperspectral imaging in UV-Vis-IR against multidimensional combat background

Abstract: Abstract Camouflage textile assessments are limited in defense research for single and multidimensional combat background (CB) against hyperspectral imaging (HSI). The development of camouflage textiles needs to be upgraded for the capabilities of modern battlefield surveillance. The purpose of this simulation work is to design remote sensing methodology and desired spectral properties of camouflage textiles. A spectral signal (SL) of camouflage textile was hypothetically simulated against dry leaves, green leaves, tree bark-woodland, water-marine, sand-desertland, stone-stoneland, snow-snowland, sky and ice-iceland CB (DGTWSIB), and a simultaneous CB of woodland-marine and marine-desert for camouflage textiles assessment. This simulation is to establish SL assessment technique of object-background (OB) in ultraviolet (UV), visible (Vis) and infrared (IR) illumination in terms of HSI spectrometry, near infrared spectrophotometry (NIRS) and Fourier transform infrared spectrometry (FTIRS) for the advancement and establishment of camouflage textiles assessment. The broad geographical DGTWSIB of camouflage textiles has been contemplated for spectral reflection in OB environments for concealment, detection, recognition, and identification (CDRI). Theoretical simulation of SL has been derived for assessment of camouflage textiles compared with single, simultaneous, and adaptive backgrounds from military CB or locations. The hypothetical and methodological model will direct advanced formulation of camouflage textile measurement for combat mechanism of reflection-SL-CDRI-OB-DGTWSIB-UV-Vis-IR (100–10,000 nm) against defense threat of HSI.

Spectral simulation and materials design for camouflage textiles coloration against materials of multidimensional combat backgrounds in visible and near infrared spectrums

Abstract: Visible and near infrared spectra of “sixteen materials for textile coloration/finishing/patterning” such as titanium dioxide, calcium oxide, aluminum, tin metal, tin oxide, iron powder, boron carbide, magnesium powder, carbon black pigment, titanium carbide, isolan black 2S LDN, isolan orange, telon blue A 2R, telon red A 2R, telon violet 3R, and telon yellow A 2R; and ‘nine materials of combat backgrounds (CBs) such as dry leaves, green leaves, tree bark-woodland CB; water-marine CB; sand-desertland CB; stone-stoneland CB; snow-snowland CB; sky CB; and ice-iceland CB (DGTWSIB) are obtained by Fourier transform infrared spectrophotometry and colorflex EZ spectrophotometer. A method of ‘Monte Carlo cross validation’ was applied for spectral simulation in visible and near infrared spectrums through experimental data information. The characterized reflection spectra of zero reflection (ZR), low reflection (LR), high reflection (HR), and HR–LR (HLR) materials are coalesced and simulated for camouflage materials design and textile applications against multidimensional CBs, DGTWSIB. The reflections of aluminum, titanium dioxide, calcium oxide, tin metal, tin oxide, and iron powder are irradiated as HR materials. Oppositely boron carbide, magnesium powder, carbon black pigment, and titanium carbide are illuminated as LR materials. Consequently, the mixing principle of HR and LR materials are also classified as HLR materials. Spectral properties of CB materials are also depicted as ZR materials against selected CBs. Spectral signal of ZR, LR, HR, and HLR materials are identified as more expedient camouflage materials for concealment of target signature than six selected synthetic dyes such as Isolan Black 2S LDN, Isolan Orange, Telon Blue A 2R, Telon Red A 2R, Telon Violet 3R, and Telon Yellow A 2R. The reflection spectra of ZR, LR, HR, and HLR materials are simulated and correlated against DGTWSIB in visible and NIR spectrums. Simulated spectral signals are considered for camouflage materials design and camouflage textiles formulation against DGTWSIB combat location, the CBs are mostly practiced by defence professional. Furthermore, the reflection principle of camouflage textiles coloration/finishing/patterning has been accumulated under spectral signal of DGTWSIB, camouflage materials and synthetic dyes, synthetic dye–metal and synthetic dye–pigment combination. Therefore, depth analysis and graphical results of ZR, LR, HR, and HLR materials are the potential findings for selection of camouflage materials, right development of camouflage textile products, and camouflage assessment of hyperspectral imaging for defence protection in the entire spectrums of UV–Vis–IR. This optical parameters of ZR, LR, HR, and HLR materials have also applications to the materials community of multidimensional branches of material research. Graphical abstract
