| 摘 要： | 为了解决各调频发射机开机时载波不同步(即载波初始相位不同)引起的相位差对天线阵列方向图的影响,提出了利用Hilbert变换测量相位差的方法,并且介绍了一种有效的相位补偿方法,即利用Hilbert变换获得相邻2个调频发射机输出信号的相位差,然后将相位差作为补偿算法的输入参数去补偿因载波不同步引起的相位差。仿真实验表明:采用该方法可以有效解决因载波不同步引起的相位差对天线阵列方向图的影响。

| Abstract: | When the transmitters work,there would exit an initial phase difference between different carrier waves,which causes serious influence on calculating the pattern of an antenna array.A method of measuring phase difference based on Hilbert transform was proposed,and an effective method of phase compensation was also introduced.The phase difference of the transmitter's output signals was obtained by Hilbert transform,and then was taken as a parameter of the compensation algorithm to compensate the phase differ... |
