optimum orientation of air flow

From the point of view of the error compensation, the lateral offset error compensation of the sub-reflector is discussed and calculated by applying the best re-pointing technique.

建立40m口径天线结构的有限元分析模型,依据有限元分析结果,对副面和馈源偏离理想位置的偏移量和偏移误差进行分析与计算;从误差补偿角度,运用最佳指向技术对副面横偏误差进行补偿分析计算。
