The invention relates to a multi-objective and near-field source locating method and a multi-objective and near-field source locating device, belonging to the field of array signal processing. The method comprises the steps of receiving target signals by a sensor array; preprocessing the signals received by all sensors; forming a plurality of receiving matrixes by the sampled and received signals; solving a plurality of covariance matrix eigenvalues and eigenvectors to form a noise subspace; carrying out spectral peak search to obtain location parameters; displaying the location result by a display circuit. The method has the essence of simplifying a Jacobi method for eigenvalue decomposition, so that the time is not consumed for selecting matrix absolute value maximum elements; a way of classification spectral peak search is adopted, so that the program running time is shortened. The device comprises a receiving sensor array, a signal preprocessing module and an algorithm implementation and location result display module. The method and the device are suitable for multiple near-field source location algorithms, and are capable of improving the operating efficiency of the near-field source location algorithms, so that multi-objective and high-accuracy location parameters can be obtained in real time.
