摘　　要：某导航设备相控阵天线主要由天线阵子、移相器和控制单元组成,移相器负责对天线阵子的相位进行实时控制。为了消除设备相控阵天线移相器之间的相位偏差,提出一种基于System Generator的快速傅里叶变换(FFT)相位求解技术,通过System Generator快速构建设备相控阵天线移相器相位解算模型,完成相位解算和补偿工作。经验证,该方法能有效缩短设计人员软件编程时间,具有较强的使用价值。Navigation equipment phased array antenna is mainly composed of atenna array,phase shifter and control unit.Phase shifter is responsible for real-time phase control of antenna array.In order to eliminate the phase deviation between phasers of navigation equipment phased array antenna,an Fast Fourier Transform(FFT)phase solving technology based on system generator is proposed,and the phase solving model of phaser of navigation equipment phased array antenna is rapidly constructed by system generator to complete the phase solving and compensation work.It has been proved that the method can effectively shorten the programming time of the designer and has strong application value.
