Study on application-oriented evaluation method for stealth materials
The performance verification and evaluation of stealth materials are a crucial part in the research&deve-lopment(R&D)and application cycle of high-performance stealth materials.In order to solve the problems such as single content and incomplete evaluation method of stealth materials,a new evaluation method for application-ori-ented stealth materials is proposed.The method improves the shape of the test specimen to weaken the interference of the non-examination scattering source on the test results as much as possible.In addition,the area integration method is further utilized to weight the area integration of the test data in multiple bands,and a comprehensive quantitative evaluation is made on the key performance of stealth materials.This method has been applied in the op-timization process of stealth materials for a typical stealth combat aircraft,and practice has shown that:the method is oriented to practical engineering needs,fully characterizes the key stealth performance of stealth materials in prac-tical application scenarios.It has the characteristics of comprehensive and accurate evaluation,providing a new ap-proach for the comprehensive evaluation of the key absorption performance of stealth materials in all frequency bands.
