| 摘 要： | 近场天线测量中，采用大的采样间隔，有利于提高测试和数据处理的效率。本文提出一种改进的采样间隔选取原则，并通过分析采样间隔与无混叠误差方向图角域的关系，说明该采样原则比文献提出的采样原则更合理。

| Abstract: | The larger sampling spacing is advantageous to enhance the measurement and data processing efficiencies for near field antenna measurements. A criterion modified for selection of sampling spacing is presented in this paper. The relation of the allowable maximum sampling spacing to the maximum angle for aliased free patterns is also analyzed, which confirms that the criterion is more reasonable than one proposed by other literature. |
