Abstract
A system and method for autonomous monitoring and active defense of lightning includes a current sensor installed on a metal object, an antenna installed near the current sensor, a signal processing and warning module (SPWM), which is configured to detect received current and field pulse signals, and issuing an early warning signal when detecting origination and development of pulses of a downward stepped leader and an upward leader, where the early warning signal is sent to a controlled surge protection device (CSPD) and/or a polarized reconfigurable lightning protection antenna, and the CSPD completes on/off actions before a first return stroke and/or the lightning protection antenna becomes only to receive/transmit horizontally polarized electromagnetic waves.
