Abstract
This paper proposes a new localization algorithm to locate the targets in non-line-of-sight (NLOS) environment by maneuverable single station. The algorithm first estimates scatters’ positions in the second layer and the distances from the second-layer scatters to the mobile station (MS) based on the circular motion characteristics. Second, by selecting the second-layer scatters as the virtual base station (BS), we can convert the problem of single station localization into the one with multiple stations. Third, the time difference of arrival (TDOA) algorithm is used to estimate the positions of the first-layer scatters. Finally, we will use the positions of the first-layer scatters and the angle of departure (AOD) to estimate the real positions of MS. The efficiency of our proposed algorithm is verified based on the simulation in a simple two-layer scattering model.
