A novel automated detection of electromagnetic fields due to lightning strokes

The development of a novel lightning detection system is presented. The system is based on the measurement of electromagnetic fields due to lightning return stroke channel, and offers distinct features, including distortionless signal amplification and intelligent triggering facility. The intelligent triggering unit is capable of rejecting unwanted transient signals such as switching signals, cloud-to-cloud lightning signals, etc. In order to calibrate the system, a laboratory lightning pulse-generator kit is developed. This calibration kit can generate simulated lightning signals in an electromagnetically polluted environment with noise and unwanted signals
