基于距离差分法消除天线测试多径干扰

摘要

在暗室中对天线进行测量时，来自暗室侧壁、后墙的多径干扰会影响测试精度。因此多径干扰成为影响天线测量精度的主要因素之一。为此，提出利用距离差分法消除天线测试时的多径干扰，达到去除多径干扰的目的。并通过数值仿真验证了该方法是行之有效的。%When the antenna is tested in the anechoic chamber,the test precision is affected by the multipath signals coming from the side wall and back wall of the anechoic chamber. Multipath interference has become one of the main factors in-fluencing the antenna test precision. Therefore,the distance difference method is proposed in this paper to eliminate the multipath interference in antenna testing. The result of the numerical simulation proved the validity and reliability of this method.
