As one of the most important target characteristics of warship，electric field signal constitutes serious threat to the vitality and combat effectiveness of warship. Based on the generation mechanism of warship’s electric field，this paper explains the classification and source of warship’s electric field，and introduces the progress of foreign electric field detecting systems，technology of sensors，data acquisition，modeling analysis，etc. The technical situation of advanced electric field fuze mines，electric field mine-sweeping and electric field protective device in the world are also introduced．This paper provides reference and improvement for domestic development of electric field fuze mines，electric field mine-sweeping and electric field protective device technologies.
