Abstract
A method includes detecting, by a pair sensors located at two locations, a radio wave generated from a lightning discharge occurring; for the pair of sensors, determining propagation paths between the discharge and sensors; repeating the same with a second pair of sensors and another lightning discharge; for each path, determine path vectors defined by an attenuation coefficient vector; constructing a matrix with each row comprising the difference between path vectors from sensor pair measurements from the lightning discharge and including a selection entry based on the identification of the sensors to enable the logarithm of sensor calibration factors to be solved for; constructing another vector, where each entry comprises the difference between the logarithms of the sensor amplitudes from a sensor pair measurement adjusted by a logarithm of an offset; inverting a system of linear equations defined by the matrix to solve for attenuation and sensor calibration factors.
