A Scaled Simulated Method of Sea Clutter Based on Non-metal Materials
A new method of the simulated sea clutter in laboratory was proposed in this paper.By employing the scaled measurement technology,we can obtain the electromagnetic scattering characteristics of different sea states.According to the dielectric properties of non-metallic materials construction technique,a new kind of composite material has been constructed by epoxy mixing metal powder and material reflectivity and complex permittivity meet the electromagnetic character of scaled simulated seawater.The materials permittivity can be controlled over a broad range.According to the geometric similarity conditions of scaled principle,the digital data of the different sea states surface scaled model is generated basing on the classic sea spectrum model proposed by the oceanographer.The sea surface waveform of the scaled material is processed by CNC machine.We have measured the reflectivity and RCS with the incident angle of scaled PM(Pierson-Moskowitz)spectrum sea surface model made of the composite material proposed,and compared the results with theoretical simulation.The compared results verify the feasibility of the scaled simulated sea surface based on non-metal materials.
