Resumé

Direction of arrival (DOA) estimation has typically played a key role in signal processing. Its task is to find the directions impinging on an array antenna to increase the performance of the received signal. To use DOA estimation methods that are applicable to most environments has become the key of technique implementation. The traditional algorithms can get superior performance for DOA estimation in the rich receiving conditions, but they are not fit for adverse environment such as low SNR, small number of array elements or snapshots, etc. In order to improve the performance of DOA estimation, the modified method based on wavelet operator is used. Moreover, the method is applied on DOA estimation algorithm multiple signal classification (MUSIC) to get new algorithm WMUSIC. Undoubtedly, the wavelet-based method expands the application range of traditional DOA estimation algorithms and has widely practical prospects in future. Further results are improved to minimize the errors in angle estimation by using genetic algorithm.   Keywords: Direction of arrival, MUSIC, SNR  Cite this Article Jadhav SS, Ganage DG, Wagh SA.
