摘　　要： 介绍了基于傅里叶分析的旋转矢量算法(REV),并将该算法应用于相控阵天线各单元的初始幅相误差校正,给出了它的仿真分析和工程实现方法;所使用的校正方法区别于以往采用的REV校正方法,利于减少校正天线对相控阵收发信号的影响;仿真结果显示,校正后各通道的相位和幅度与人为设置的相位、幅度只差一个常数,表明方法是有效的;通过实际测试,校正后的天线方向图与近场校正结果逼近,EIRP比校正前提高1.4dB以上,验证了校正方法的功能和性能。 The REV algorithm for correcting the initial amplitude and phase error of the phased array antenna hased on Fourier analysis is introduced, and its simulation as well as engineering realization method is given. The given method, which can reduce the interference of -he correction antenna to the communication signals, is different from traditional REV method. The simulation result shows that, the amplitude and phase after correction for each element has only a constant difference from the one before correction, which can proof the effection of the given method. Through actual test, the antenna pattern has a good approximation to the pattern after near field correction, the E1RP in creased for more than 1.4 dB, compared with the one before REV correction, and the function as well as performance of the given method is verified.
