Abstract:The performance verification and evaluation of stealth materials is a crucial part in the 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-oriented stealth materials was 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, which is characterized by comprehensive and accurate evaluation. The method is oriented to practical engineering needs, fully characterizes the key stealth performance of stealth materials in practical application scenarios, provides a new way for comprehensive evaluation of the key wave-absorbing performance of stealth materials in all frequency bands, and has completed its application in the stealth material selection process of typical stealth combat aircraft.
