【摘要】：针对目前平面近远场变换中,探头H面方向图对天线远区副瓣引入误差较大的情况,研究了一种基于E面电场-边缘电流逼近混合算法的探头补偿。通过在微波暗室对某频段阵列天线测量,并分别用E面电场法、边缘电流逼近法以及混合算法进行近远场变换。结果表明,此方法集合了前两种方法的优点,从而使副瓣精度有明显的提高,证明了该方法的有效性和工程实用性。
[Abstract]:In the current plane near-far field transformation, the probe H-plane directional pattern introduces a large error to the far side lobe of the antenna. A probe compensation based on the E-plane electric field-edge current approximation hybrid algorithm is studied. The antenna array in a certain frequency band is measured in the microwave anechoic chamber, and the near-far field transformation is carried out by using the E-plane electric field method, the edge current approximation method and the hybrid algorithm respectively. The results show that this method combines the advantages of the first two methods and improves the precision of sidelobe obviously. The validity and engineering practicability of this method are proved.
