卫星多波束天线赋形理论的研究

The Study of Theory on Shaped Beams for Satellite Antennas

采用最小ｐ乘法优化卫星多波束天线的馈源激励系数，纠正了文献［１］中错误的优化公式，并采用了下降法中的变尺度法进行计算，大大减少了迭代次数．还给出了本天线设计中必不可少的一套通用的坐标变换公式．最后通过一个简单的计算实例进行了验证．

Uses the least pth method to optimize the excitation coefficients of multibeam satellite antennas, and corrects the wrong formula in paper . In the computation, the Fletcher Powell optimization algorithm is used, and this most reduces the iteration numbers. General coordinates transform formulas are also given. Finally, a simple example is used to test the theory. The theory can be used as a reference to the designers of shaped beams for satellite antennas.
