Research on underground pipeline localization based on multimodal sparrow search algorithm

Aiming at the problems of high computational complexity and poor real-time performance when MUSIC algorithm is used in multi-dimensional traversal search for underground target location, a multi-modal Sparrow MUSIC fast underground target location algorithm is proposed. The results of simulation and experiment show that the proposed algorithm has high localization accuracy, and compared with the 2D-MUSIC algorithm the average time for target localization is only 1.07%. In addition, compared with the same type of algorithms, the proposed algorithm has a higher search success rate.
