Study on Navy Ship Lightning Waveform and Protection Test

Ships have dense electronic information and weapon systems. With the continuous expansion of missions and active sea areas, ships performing missions at sea are facing increasingly prominent lightning hazards. Ships have complex structural characteristics such as large hull size, numerous masts and various abrupt antennas on the platform. Aiming at difficulties and key problems such as the change of waveform characteristics and complex test after lightning acts on ships, using the analysis method based on the attraction area, the integrated model of lightning channel, ship and main mast system is established, the effect of lightning on ship is analyzed, the characteristics and parameter changes of ship lightning effect waveform are obtained, the selection of different ship zoning and test waveform are put forward, the test items and test procedures of ship lightning protection are determined, and the test methods of key items are proposed. The verification test is carried out to provide technical support for improving the survivability and combat effectiveness of ships in the lightning strong electromagnetic environment.
