Abstract
The interferometer is a kind of passive positioning device with significant military value. Most of the passive positioning method require long convergence time and acquire low precision. The Doppler frequency shift is used in immobile radiation source positioning by extended Kalman filtering algorithm. This method has high precision, fast convergence and not sensitive to the initial conditions. The simulation results demonstrate the effectiveness of the algorithm.
