Naval mine detection system based of FPGA circuit

Electrochemical processes take place in a metal object immersed into sea water even if an anticorrosive coating is applied [1]. As a result, flowing field appears around the object. There are naval mines between many other objects situated in the sea. Naval mines can be put in the seabed in order to be more difficult to detect by sonars. Such a mine is located on the line demarking two environments of different electrical conductivity. The results of a computer analysis of the influence of seabed’s electrical conductivity on the electric field’s disposition around a mine model are shown below. Also, a naval mine detection system based on the FPGA circuit is presented.
