S matrix theory of the ship degaussing system and its measurement

So\|called S matrix theory of the ship degaussing system is set up which can be used for simulating the degaussing currents in any attitude under certain action of the earth's magnetic field. A series of measuring and analyzing steps are put forward to get the matrix, including the measurement of the degaussing currents on the four main magnetic directions and the measurement of the degaussing current to rolling angle on the east direction. The matrix could also be used to solve the problem of the quick anti\|interference of the degaussing system.
