Research on Stealth Target Coat Damage Detection Based on Hilbert Huang Transform

The stealth coat on the surface can help target escaping from being detected by enemy radar, making the stealth target an import role on the modern war. But the coat will be damaged during the transformation, training and other situations, which can reduce the hiding peculiarity of the target, using Hilbert Huang Transform we can get the identity of the damaged target echo, realizing the stealth target coating damage detection, after improving Hilbert Huang Transform, this paper obtain a new Hilbert Huang Transform method which can be applied to detect the stealth target coating damage and obtain an effective result.
