Abstract Aiming at the problems of high computational complexity and poor real-time performance whenMUSIC (Multiple Signal Classification ) algorithm is used in multi-dimensional traversal search for underground target location，a multi-modal Sparrow MUSIC fast underground target location algorithm is proposed．In this algorithm，the guidance vector model under the ground detection model is established．Therefore，the application of the MUSIC algorithm is extended to the underground pipeline location．Sparrow search algorithm powerful searching ability and convergence speed，which can be combined with MUSIC algorithm to achieve fast positioning．In view of the problem that the classical sparrow search algorithm cannot search multiple spectral peaks，the cluster algorithm is used to divide the sparrow population，so that the
sparrow population can form multiple subpopulations to search the peaks in parallel．Moreover，the combination
with the particle swarm optimization algorithm ensures the local search at the peaks．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 0．979%．In addition，compared with the same type of algorithms，the proposed algorithm has a higher search success rate．
