| Abstract: | An active method is proposed to realize me magneuc sensor po~Juu.m~, ~ e of the sea. Using a magnetic source treated as a magnetic dipole and the corresponding vector formula, we deduced an analytical expression of the vector between the magnetic source and the sensor, thus making it possible that we could confirm the position of the sensor quickly and accurately. The analytical formula can also be used to detect other magnetic objects and realize the recognition under water. |
