摘要
研究了干扰环境中部分极化信号的最佳滤波问题,以信号干扰噪声比为优化对象,建立了带约 束非线性优化模型,利用拉格朗日乘子法和参量矩阵的反对称性,将非线性最优化问题巧妙地转化为二次代 数方程求根问题,得到了最优化问题两个备选解的解析表达式,给出了完整解法.
The problem of optimal polarization filtering of partially polarized signals in the interference background is studied. With the index of Signal-to-Interference-and-Noise-Ratio (SINR) as the optimization object, a nonlinear optimization model is built. With the help of Lagrange multiplier method and properties of asymmetric matrix, the problem of SINR optimization is transferred to a root problem of a quadratic equation. Analytical expressions of two candidate solutions are achieved and the complete algorithm is presented.
