This article gives a brief summary on VHF pulse radiation associated with lightning discharges and its location. There are two independent techniques: Time of Arrival and Interferometry. VHF pulses are believed to be emitted during all of the processes of a lightning discharge. Thus, the mapping of VHF pulses associated with lightning yields information not only on lightning channel, but also on the charge distribution. On the other hand, both systems have advantages and disadvantages over each other, and this article summarizes both principles.
