Zusammenfassung:The invention discloses a double-linear-array focusing beam forming passive positioning method based on deconvolution, and relates to the technical field of passive localization, the method utilizes a receiving array of a double-linear-array structure to be combined with focusing beam forming to obtain a sound source distribution diagram, compared with a conventional method of adopting a single-linear-array structure, the method can improve the port and starboard distinguishing capability, and the positioning accuracy is improved. And the obtained sound source distribution diagram is not directly used for positioning, but is subjected to deconvolution operation with a near-field directivity function obtained by calculation according to formation parameters of the receiving array to finally obtain a sound source positioning result, so that the positioning precision and accuracy are further improved, the resolution is higher, the side lobe is lower, and the positioning accuracy is higher. And the method has bet
