This paper handles a proposed Anti-stealth technique for countering radar absorbent material stealth Technology through enhancing material electric permittivity. EM3500 wave absorber was used for the experimental work which its optical properties exhibit stealth characteristics with absorption coefficient 3.61566 and reflection coefficient 0.041 at wavelength 300 nm and frequency 1 MHz The enhancing of electric permittivity and decreasing loss tangent was performed by using non-lethal ND YAG 532nm. impedance Analyzer Agilent test results shows increasing the EM3500 electric permittivity with percentage 11.5% at frequency band 1MHZ and 5.5% at 3Ghz also decreasing it's loss tangent with 27.7% at 1Mhz and 7.5 % at 3Ghz. The research problem is implementing anti stealth technique in invisible dynamic environment as the structure of offensive target is uncertain. So there are considerations for making unmanned aerial vehicle defensive by covering its surface with certain number of laser beam firing angle according to its dimensions. These laser beams create symmetric geometries transverse to aircraft which is the expected dimensions of offensive stealth target. the accuracy of the system is determined through the mathematical modeling of laser beam firing angle. Model predictive control and fuzzy logic control were used for controlling laser beam firing angle for covering the unmanned aerial vehicle surface and achieving intelligent geometry for the uncertain target structure. If the target's permittivity increased the electromagnetic waves can detect the target then destroying it by using pulsed laser beam, this monograph is future research for enhancing anti stealth implementation.
