Development of a Lightning Location System Based on Electromagnetic Time Reversal: Technical Challenges and Expected Gain

The basic principles on which commercial Lightning Location Systems are based have not changed since their inception and the research and innovation efforts in the field have been essentially aimed at refining the location accuracy and at improving the discrimination and grouping algorithms of different types of lightning. Time Reversal is a promising technique that has recently received attention for source location and has been shown to be applicable to lightning location with improved performance. This paper describes the technique and the challenges involved in the development of such a system.
