| 摘 要： | 由于坐标系统不统一以及空间曲面方程的复杂性等，雷达天线表面检测是一个非线性求解问题。提出了改进的遗传算法求解雷达曲面方程拟合中的坐标平移、旋转以及曲面标准方程的参数。在一个工程实例中的应用和比较结果表明，遗传算法能够应用于雷达天线等曲面拟合，改进算法更具优势。

| Abstract: | As coordinate system is not uniform and spatial surface equation is complex, radar antenna surface detection turns to be a nonlinear problem. This paper proposes to calculate the parameters of coordinate translation, rotation and surface standard equation with the method of parameter identification based on improved genetic al- gorithm. The application in an exact project shows that the improved genetic algorithm can be well used to surface fitting, such as radar antenna and is superior to the traditional one. |
