摘要：
Complex operating environmental loads lead to structure deformation of active phased array antennas (APAA), which could finally seriously degrade the electromagnetic performance of antennas. Based on the electromechanical coupling model of APAA, the phase compensation method is applied to recover the electromagnetic performance of the deformed antenna to the ideal performance as much as possible, where the excitation phase adjustment quantity of element is derived, and the application range of the method is discussed. Finally, the effectiveness of the method is verified by experiments on an APAA with 24x32 elements to compensate the effect of typical deformation in the operating environment. The work can provide theoretical basis to guarantee the electromagnetic performance of APAAs in real time.
