采用Nelder-Mead单纯形算法实现了等离子体隐身时多个等离子体参数的优化反演,初步解决了隐身应用研究中等离子体参数的局部最优取值问题.反演结果表明,对于非磁化均匀冷等离子体,在选定的参数取值范围内,吸收程度由等离子体的电子密度、碰撞频率及等离子体层厚度共同决定.等离子体层厚度决定了最佳吸收波长,且当入射雷达波频率大于某一频率时,等离子体碰撞频率趋于一个稳定值.%The multi-parameter optimization of plasma was performed by using the Nelder-Mead algorithm for getting the optimal point, and the optimal solution of plasma's parameters in stealth application was solved. The results of the parametric inversion show that in the spans of the parameters against the nonmagnetic and uniform plasma, the attenuation level was decided by the electron density, collision frequency and the thicknessrnof plasma layer. The optimal absorptive wavelength was decided by the thickness of the plasma layer, and when the frequency of the incident wave was greater than a threshold, the collision frequency of plasma was tended towards a stable value.
