ESPRIT Algorithm Baesd on Multi-stage Winner Filtering

Because of the enormous calculating quantity introduced by singular value decomposition,the direction finding algorithm based on subspace decomposition is difficult to be realized in engineering in real time.The multi-stage Wiener filtering (MSWF) algorithm avoids the singular value decomposition calculation,reduces the calculating quantity effectively.This paper puts forward an estimation method of source number by improving MSWF algorithm.The algorithm improves the direction-finding accuracy compared with traditional MSWF algorithms.The validity of this algorithm is validated through simulation.
