摘　　要：本文提出一种修正近场天线测量中探头位置误差的方法——非线性迭代法。探头的位置误差为可知值 ,由激光定位系统获得。运用泰勒级数展开 ,可将天线理想波谱表示为误差算子和近场测量数据的形式。通过计算机模拟 ,得到迭代修正后精确的近场值。本文在理想值、有误差的值和修正误差后的值之间作了些比较 ,相应的模拟数据有助于证实此结论。A general correction technique is developed to remove probe positioning errors i n the Near-field measurements of the antenna. Probe positioning errors can be o btained with high accuracy using the laser positioning systems. The ideal spec trum of the antenna is presented by using the data measured and the error operat or with the Taylor series expansion. By computer simulation, a fairly accurate correction value can be obtained. Some comparisons between the ideal, error incl uded and corrected values are made. Appropriate graphical representations are pr esented to enhance understanding of the results.
