有源相控阵的幅相误差校正和波束形成一体化方法

有源相控阵的衰减器和移相器会随着波束形成要求的不同幅度和角度值进行调幅和调相,在实际应用中衰减器和移相器的调节会造成原始通道幅相误差发生变化,从而导致波束形成性能的恶化。文中提出一种可将幅相误差校正和波束形成同时完成的一体化方法,在校正原始通道幅相误差的同时,解决了通道幅相误差随形成波束变化而导致的波束形成性能恶化的问题,具有实现简单、运算量小等优点。理论分析和仿真结果证明了该方法的正确性和有效性。

An Integrative Beam-forming Method with the Calibration of Amplitude and Phase Error Based on Active Phased Array System

The attenuator and phase shifter of active phased array adjust the amplitude and phase with the requirement of beam forming,and the adjustment of attenuator and phase shifter will change the original amplitude and phase errors,which leads to the depravation of the performance of beam-forming in fact.An integrative beam-forming method with the calibration of amplitude and phase errors is proposed in this paper.This method calibrates the original amplitude and phase errors and resolves the variety of amplitud...
