摘　　要：以3层结构的吸波涂层为例,以误差因素模拟干扰、以信噪比为指标度量产品质量特性;采用L9(34)正交表安排可控因素,L36(23×313)安排误差因素,采用田口方法和内外表直积法进行了优化设计研究。研究表明,底层电磁参数ε=22.18-j1.82,μ=1.09-j1.81,厚度为0.3mm;中间层电磁参数ε=6.7-j0.64,μ=0.54-j0.31,厚度为0.7mm;面层电磁参数ε=10.77-j1.15,μ=1.67-j1.23,厚度为0.2mm;当频率为10GHz时,涂层厚度波动为10%的情况下,平均反射率<-10dB,具有良好的抗厚度和原材料电磁参数波动的能力。Taken the triple-layer radar absorbing coating as an example, we used error factor to simulate interference and used SNR （signal to noise ratio） as an index to evaluate the quality characteristic of the product. Based on the orthogonal table of L9 （34 ）, we arrange the controllable factors and based on the orthogonal table of L36 （2^3 × 3^13） , we arrange the error factors. According to taguchi method and cross-products of inner and outer arrays,we made specific research. The research shows that when the electromagnetic parameters of the bottom layer was ε=22.18-j1. 82 μ2=1.09-j1. 81 ,the thickness of the bottom layer was 0.3mm;electromagnetic pa- rameters of the mesosphere was e =6.7-j0.64 ,μ=-0.54-j0.31 ,the thickness of the mesosphere was 0.7mm; electromagnetic parameters of the top layer was ε=10.77-j1. 15,μ=1.67-j1. 23, the thickness of the top layer was 0.2mm;the frequency was 10GHz and the thickness of the coating fluctuates 10%, the average reflectivity was less than --10dB. It has a faculty of resisting the fluctuation of thickness and electromagnetic parame- ters.
