Site Error Correction with Time Information
International Conference on Lightning Protection (ICLP), Firenze, Italy 1996
Site error correction is an important process in the operation of a lightning location system based on magnetic direction finder technology. Different algorithms have been published in literature to correct systematic angle errors [Schulz and Diendorfer, 1993; Soerenson, 1995]. These algorithms use the angle information only for the correction, because the old version of the LLP system only provided the angle information of a flash.
With the new IMPACT technology, in addition to the angle also the arrival time of the signal at the site is measured. So it is possible to correct the site errors more efficiently by including time information in the site error algorithms.
In this paper we show, how site error correction can be performed including the time information and how the use of the additional time information improves the results.
In addition to the correction of the angular error it is also possible to correct the propagation error of the signal approximately. The improvement in data quality of the localized strokes due to the application of a time correction is evaluated.
