摘要
为了实现良好的波束形成结果,必须对相控阵天线进行校正。目前发展了很多校正算法,其中REV、CCE和UTE等方法适用于运动载体上的相控阵天线校正。由于REV不需要增加额外设备即实用性较强,所以获得了更广泛的研究,但它需要的时间与硬件资源较多。为了解决这一问题,文中提出了一种可快速有效地进行运动载体相控阵天线校正的正交四相方法。新方法通过对接收信号功率方程的降维反演来进行阵列校正,校正时间远小于REV,因此更有利于在实际中应用。
To make beamforming better, the phase array antenna （PAA） was needed to be calibrated. A series of algorithms were proposed for that now, for an instance, REV, CCE and UTE and so on were proposed for PAA on moving flats. REV was more preferred to be applied in practice for not acquiring more equipment and was given more attention. Nevertheless, REV asked for more calibration time and hard ware resources. So a new orthogonal 4-phase coding method was proposed in the paper for moving flats. The new method calibrated the PAA by using the reducing the rank of the power equation of receiving signals, which was help to fulfill the calibration process in a much shorter time than REV. It＇s testified that the new one was more preferred in practice.
