title: [Research of search strategy in the fields of double iron rotating electromagnetic locating/tracking method].
abstract: This paper introduces a new search strategy on the basis of self-adaption step, aiming at solving the problem that primary double iron rotating electro-magnetic tracking method can not make a good balance of accuracy and efficiency. Through the emulation, we can conclude that this new strategy can sharply increase the efficiency, with the accuracy identical to that of the fixed-step (0.5 degrees).
