Abstract

The invention relates to an invisible material performance decay point frequency type detection method and a system device thereof. According to the method, daily monitoring of invisible performance decay of vehicles such as invisible aircrafts and the like and early warning of failure life are realized by adopting a method of contrastive analysis of invisible performance calibration parameter values of standard new products of detected objects such as invisible aircrafts and other vehicles in different areas and invisible performance parameter values periodically monitored and detected in theservice process of the standard new products. According to the invention, by adopting a dot frequency detection mode of each waveband, the permeability and reflection characteristics of the invisiblematerial to different frequencies, namely the loss and phase shift of electric wave propagation, are detected, so that the invisible performance of the material is obtained, and relatively large bandwidth and linear detection can be realized; and the angle position of the array type microwave antenna in the detection probe can be adjusted, so that the stealth performance of different incident angles can be detected.

Description

technical field [0001] The invention relates to the technical field of detection of invisible materials in vehicles such as airplanes, in particular to the non-destructive detection of the stealth performance of radar absorbing materials, in particular to a point-frequency detection method and system device for the performance decay of stealth materials. Background technique [0002] An important feature of modern combat aircraft is the stealth function under the scanning of phased array radar. The stealth performance technology of stealth aircraft is generally included in the design of the aircraft's shape and structure, and its radar absorbing material technology. [0003] However, the shape and structure of stealth aircraft will be deformed due to bumps or stress during use, and radar absorbing materials will also be affected by various corrosion and scratches in daily use. Therefore, the stealth performance of stealth aircraft depends on its The life process with a cert...
