Abstract
In this Master Thesis we are aiming to improve current lightning imaging techniques in the radio spectrum by means of a Kalman Filter. Current LOFAR-based methods fail whenever the inter-pulse distance reaches 150 ns, and the Kalman Filter has the potential to lower this boundary. It is shown that the Kalman Filter can predict the location in time of a given pulse accurate to a few nanoseconds in most cases. Exceptions remained within a few tens of anoseconds and were only seen in the case of a crude initial estimate or deviating shapes of pulses, for which the technique still has to be optimized in the second case. Also, we show that even though we use a linearized version of the Kalman Filter in our non-linear model, the imaging can still be done close to optimality.
