| 摘 要： | 远场测量是获得天线辐射特性的一种常用方法。然而对于一维电尺寸大，另一维电尺寸小的天线，如基站天线，由于场地因素的限制，往往不能满足远场测量条件，用近场测量又费时费力。在这种准远场条件下，天线测量结果与远场情况下的测量结果有较大差异。本文基于柱面波展开，给出了一种由准远场距离上测得的方向图计算远场的理论计算方法，经过该算法补偿后的结果与理论计算结果吻合很好，从而验证了算法的正确性。

| Abstract: | Based on the calibration requirement of vector thrust field dynamic for aerospace engineering,a calibr-ation system for calibrating vector thrust test cell is introduced,using pendulum bob as the power source.In case of limited calibration points,artificial intelligence RBF neural network is applied in the calibration work to calibrate and compensate the dynamic characteristics of vector thrust.The verification result shows that the calibration systems dynamic property is excellent good.It can meet the calibration need of vector thrust，and provides a basis for the further accurate measurement of vector thrust. |
