Although lightning is a well-studied phenomenon, only recently have lightning tracking systems, like the the National Lightning Detection Network (NLDN) and the Lightning Mapping Array (LMA), given us precise timing and position of lightning strokes. Lightning produces high power, broadband, impulsive emissions originating from locations unsuitable for conventional Transmitter(s) (Tx) deployments. Leveraging these emissions as a Tx, we can form a passive RAdio frequency Detection And Ranging (Radar) system to monitor maritime traffic. This work evaluates the feasibility of such a system through real and simulated experiments. These experiments showed when, where, and how such a system would work. Were such a system built, it would significantly reduce the hardware needed to monitor maritime traffic, limit spectrum pollution, and increase the surveillance area for a very small cost.]]>
