Abstract

In this paper, four underwater source location algorithms based on energy measurement using a randomly distributed sensor array are proposed. First, closed form of least squares (LS), total least squares (TLS) and constraint least squares (CLS) formulation for single source location are derived from the definition of energy ratio between different sensor readings. Then, the maximum likelihood estimation for multiple sources is presented and the alternating projection-multiresolution (APMR) algorithm is proposed to locate multiple sources. Simulation results show that our localization algorithms achieve good performance with high computational efficiency.
