Estimation of Distributed Source 3-D DOA Using Electro-Magnetic Vector Sensor
Xiong Wei-zu · Journal of Circuits and Systems · 2004
Based on the principle that a spatial distributed source can be regarded as superposition of many of point sources in a continuous spatial area, an Electro-Magnetic Vector Sensor (EMVS) model is proposed. Theoretical analysis and the 1st order approximate expression are given. The model抯 identifiability is also discussed. To reduce the searching complexity, this algorithm only involves the angular space and polarized space searching. In special cases, even angular searching is concerned. Simulations are given to verify the validity of the analysis on the proposed model.
