Radar target identification of coated object using Cauchy method

This paper presents an object identification. The PEC sphere which is coated by different dielectrics is determined through poles extracted by using a Cauchy method. Simulations were conducted to investigate the effect of electrical property and thickness of dielectrics used to coat the PEC sphere. Poles extracted from the scattering frequency response of objects are employed to identify their properties. Simulation results show that different dielectrics and thickness of coating materials have different poles.
