摘　　要：针对大型抛物面天线反射面分块面板的特点,基于最佳吻合的概念,从机电耦合学科交叉的角度,研究了反射面分块面板的调整问题,推导出了靶标点与调整量之间的影响关系矩阵,给出了数值方法,研制了准实用软件.将程序软件应用于某实际天线中,收到了满意的结果.The errors associated with a segmented primary reflector limit the electrical performance obtainable with those antennas which employ them. It is necessary to derive the effect of panel positional error on electrical performance in order to determine panel adjustments for such reflector antennas. The transformation matrix that relates panel adjustments to surface errors in terms of best fit paraboloid （BFP） is derived.Based on the transformation matrix, a novel mathematical model and a useful program are developed. After being used in practice the results have shown that the method for panel adjustment is of efficiency.
