Abstract

Abstract: The design of coating structure is an important method to achieve the favorable absorbing capability. For the issues in the computer-aided design of cpating structure, such as low operation efficiency, optimization of single target and manual intervention, a multi-objective optimization model of radar absorbing coating with the aim of “thin-layer, light-weight, broad-band and strong-absorbing” is constructed, and an optimized project based on NSGA-Ⅱis presented.The optimized thickness of the double-layer absorbing coating composing of 3^# and 2^# materials is 0.6 mm with the reflectance of lower than -8 dB at 18~18 GHz band. Experiments show that this method can be used for the structure design of multilayered radar absorbing coating in case of prediction of redundancy.

Key words: ordnance science and technology, NSGA-Ⅱ, multilayered microwave absorbing coating, optimized design
