Abstract The Direct Position Determination (DPD) methods outperform the classic two-step localization methods in localization accuracy, while the existing DPD methods based on array antenna models do not exploit Doppler frequency shift information to improve localization accuracy further. Fusing Doppler frequency shift information, a DPD method based on array antenna model is proposed to overcome the above mentioned shortcoming. Firstly, a DPD model fusing Doppler frequency shift information is constructed. Then, a maximum likelihood estimator is designed and emitter’s position estimation is transformed to calculating the maximum eigenvalue of the matrix containing location information. The property of eigenvalue keeping unchanged after matrix transpose is used to simplify the calculation. Finally, the emitter’s position is estimated via a two-dimensional grid search. Simulations show that the proposed method is superior over the DPD methods based on array antenna models and the DPD methods only using Doppler frequency shift information in localization accuracy.
