ABSTRACT
For broadband noise source localization technology, this paper introduces different broadband sound source localization algorithms, improves the existing DCS-SOMP algorithm, and finally applies the improved DCS-SOMP algorithm to the localization of broadband sound sources of different intensities. In this paper, the performance of the improved DCS-SOMP algorithm is studied in detail from the aspects of difference of sound source intensity, number of sound sources, signal-to-noise ratio, bandwidth width, and target sparsity. By comparing with the DCS-SOMP algorithm, it is found that the improved DCS-SOMP algorithm has good stability, and can locate sound sources of different intensities when the signal-to-noise ratio is very low. The improved DCS-SOMP algorithm can also pinpoint sound sources of different intensities when locating multiple sound sources. The case application shows that the proposed method can achieve the goal of locating broadband noise sources at different center frequencies at the same time, and can be used for various types of leakage noise detection.
