提出了一种宽带脉冲电磁干扰测向技术。利用火花发生器作为脉冲噪声源进行了实验研究。使用以1 Gs/s直接采样的双天线阵列捕获信号。基于数字信号处理的相关技术允许评估天线之间的时间延迟。在非理想电波传播环境下的实验结果表明，该方法的方位估计精度可达20。
A direction-finding technique for wide-band impulsive electromagnetic interference is presented. An experimental investigation was performed using a spark generator as the impulsive noise source. The signals were captured using a two-antenna array directly sampled at 1 Gs/s. A digital signal processing based correlation technique allowed assessment of the time delay between the antennas. The results in a nonideal radio propagation environment show the bearing can be estimated to an accuracy of 20.
