以对数周期天线阵为基础,提出了一种相位波前分析测向方法,该方法直接对天线阵信号的相位响应进行处理得到来波信号方位,不需要对天线相位中心进行复杂的计算和校准,较好地克服了常规测向算法对相位中心的依赖性。计算机仿真分析结果验证了该方法的有效性。
Based on the logarithmic periodic array, a method of phase-wavefront analysis and direction finding is proposed. The method directly processes the phase response of the antenna array signal to obtain the direction of the incoming wave signal. It does not need to calculate the phase center of the antenna complexly. Calibration, better overcome the dependence of the conventional direction finding algorithm on the phase center. Computer simulation results verify the effectiveness of this method.
