Representational reflectivity failure evaluation method of wave-absorbing material

Abstract

The invention discloses a representational reflectivity failure evaluation method of a wave-absorbing material. The representational reflectivity failure evaluation method of the wave-absorbing material comprises the steps of: for the characteristics of stealth weapon equipment, in combination with the representational reflectivity distribution characteristics of a wave-absorbing material coated on the stealth weapon equipment, determining information of representational reflectivity characteristic points of the stealth weapon equipment; measuring the determined representational reflectivity characteristic points, creating a representational reflectivity benchmark database of all characteristic points, and storing; after the stealth weapon equipment is delivered to a user and used after aperiod of time, according to the distribution characteristics of the representational reflectivity characteristic points of the stealth weapon equipment, in combination with the visual inspection result of the wave-absorbing material coated on the stealth weapon equipment, determining a characteristic point to be evaluated; and, measuring the representational reflectivity of the characteristic point to be evaluated, comparing the representational reflectivity of the wave-absorbing material of the characteristic point obtained by measurement with the corresponding result in the benchmark database, and evaluating and determining the maintenance priority. By means of the method, the representational reflectivity of the wave-absorbing material at the position of the measured target characteristic point and a frequency relation curve can be directly obtained; furthermore, whether the representational reflectivity of the wave-absorbing material at the position of the feature point loses efficacy or not can be evaluated; the failure evaluation cost of the stealth weapon equipment is obviously reduced; the failure evaluation period is shortened; and the failure evaluation efficiency is increased.

Description

technical field [0001] The invention relates to the field of measurement and evaluation of the characteristic reflectance of a wave-absorbing material, and more specifically, relates to a method for evaluating the failure of the wave-absorbing material to characterize the reflectivity. Background technique [0002] In recent years, with the maturity of radar wave stealth technology and its wide application in military equipment, stealth weapons and equipment have been installed in troops one after another. In the design and development process of stealth weapons and equipment, in order to achieve the overall stealth effect of weapons and equipment, in addition to the plastic design of weapons and equipment, a large number of different types, different specifications, and different thicknesses of absorbent are applied to different parts of stealth weapons and equipment. wave material. After the stealth weapons and equipment pass the factory inspection and are delivered to th...

Problems solved by technology

However, after the stealth weaponry is delivered to the user, neither the surface of the stealth weaponry coated with absorbing material nor the environment in which the stealth weaponry is located cannot meet the identification and measurement requirements stipulated by the national military standard.
