Taylor series approximation for estimation of vector sensor array misorientation

Based on the difference between ideal electromagnetic vectors and misorientation electromagnetic vectors, a novel estimation method using two reference signals with unknown parameters is presented. When electromagnetic vector sensor array misorientates, the vector sensor deviates from its normal orientation and error is caused. Subspace algorithm based on eigenvalue decomposition is very sensitive to error, thus it is necessary to calibrate it. The computational formulas of the misorientation errors are derived in this paper. Finally, Simulation results verify the effectiveness of the new algorithm.
