Abstract:
The detection efficiency (DE) of the ADTD Lightning Location Network and the sensors in Beijing is evaluated by using the dataset of 2012 to 2016 with 134 million strokes detected by 13 sensors in the BeijingTianjinHebei area. The DE for the sensors in Beijing varies at different distances and azimuths from the sensors, and the effective detection range is within 260 km. The DE for the sensors in Beijing has a low value of 195% within 20 km, and gradually increases to a maximum value of 869% from 60 km to 80 km， and then goes down from 80 km. As for the azimuth, the DE of the sensors has a lowest value of 243% in north by northwest, which reflects the influence of the orthogonal magnetic antenna on DE. The total DE of the entire network in Beijing with selfevaluation is estimated between 85% and 95%, and the DE for the strokes with lower current is unsatisfactory.
