Recalculation of Lightning Localization System Acceptance Using a Refined Damping Model

Abstract

Acceptance of lightning detectors and lightning localization systems has been investigated. Previous calculations based on an exponential damping of the lightning radiation pulse have been repeated using a more sophisticated model for the damping. Both peak amplitude damping and change of rise time have been considered. The land/water distribution with different conductivities has also been included in the calculation. The results and conclusions from the earlier model which shows the strong damping influence and helps to optimize lightning localization systems have been confirmed. The differences in the results between the exponential damping model used previously and the present new model are small. A further increase of the model accuracy, therefore, has no practical use due to the uncertainties of the equipment parameters.
