Abstract
The present invention relates to a system and method for detecting lightning activity. When a lightning strike is close enough to a receiver, the strength of the signal received will cause the receiver to saturate. In such a situation, a non-filtered signal is used to calculate a range and bearing. In one specific embodiment, a receiver detects energy emitted by a lightning strike and separates the lightning strike to a filtered signal and non-filtered signal. A saturation detector determines if the filtered signal is saturated prior to the filtered signal being filtered. In response to the filtered signal being saturated, a processor processes the non-filtered signal from the receiver, estimates locations of the detected lightning strike relative to the system, determines a cumulative effect of the lightning strike spaced in distance and time, and generates display signals to illustrate the cumulative effect with respect to a grid.
