College of Information and Electronic Engineering, Shandong University of Science and Technology, Shandong Qingdao 266510, China)Abstract: It is important for mine corp. to make their produce safe and efficient that underground people are exactly located. This article expounds three mainly electromagnetic wave location methods and analyses the feasibility of Time of Arrival (TOA) method. Furthermore it proposes a superresolution TOA method based on subspace deposition and MUSIC algorithm to resolve time resolution of TOA. The MUSIC TDE algorithm is simulated in the two typical conditions DLOS and OLOS, and the results sho
