A direction-finding technique for wide-band impulsive noise source
C. Peck, Philip J. Moore · IEEE Transactions on Electromagnetic Compatibility · 2001
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.
