【摘要】:針對目前平面近遠(yuǎn)場變換中,探頭H面方向圖對天線遠(yuǎn)區(qū)副瓣引入誤差較大的情況,研究了一種基于E面電場-邊緣電流逼近混合算法的探頭補(bǔ)償。通過在微波暗室對某頻段陣列天線測量,并分別用E面電場法、邊緣電流逼近法以及混合算法進(jìn)行近遠(yuǎn)場變換。結(jié)果表明,此方法集合了前兩種方法的優(yōu)點,從而使副瓣精度有明顯的提高,證明了該方法的有效性和工程實用性。
[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.
