Relationships between the RCSR Properties of a Coated Slab and Absorbing Characteristic of the Coated RAM
Relationships between the radar cross section reduction(RCSR)properties of a coated slab and the characteristic of the coated radar absorbing materials(RAM)are studied.The slab with radar cross section(RCS)patterns coated with RAM are calculated for either horizontal polarization(HH)or vertical polarization(V V)incident plane wave using a uniform geometrical theory of diffraction for loss surfaces.Comparing the reflection or absorption characteristic of the RAM to the properties of the bi-static RCS of the coated slab,approximate analysis results show that the two are dependent.Surface waves are considered wherever there is reactive surface impedance.The mono-static RCS of the coated slab can be mainly benefited from edge effectiveness for surface wave.The attenuation constants of surface wave in the coated RAM are analyzed.Examining the RCS patterns,we can observe that the effect of RCSR for the coated slab can achieve an optimum at 75° of incidence angle,which can be also interpreted from the characteristic of the coated RAM.The most difficult part in the RCSR design occurs at low frequency,which can be improved by optimizing the characteristic of the coated RAM.
