A Numerical Least Squares Analysis of Electromagnetic Compatibility

Analysis strategies of nonlinear electromagnetic interference have always been a focus in the literature. This paper designs a identification of scattering pattern by using a improved least squares method (LLM) combined with method of moment for mutual coupling among inner elements and interactions with outside scatterers. The novel LLM is applied to optimize the radiation pattern of arbitrary arrays in the operational environment as well as represses the array gain and phase tracking error caused by electromagnetic compatibility based constraints. The algorithm has a simple control structure and enhances the robustness of the electrical system, and the experimental results based on dSPACE testify its reasonability and validity.
