  • Target positioning device and method based on plecotus auritus double-pinna bionic sonar
    Patent number: 11346942
    Abstract: A target positioning device and method based on a plecotus auritus double-pinna bionic sonar. An echo positioning device based on bionic pinnae of a bat can determine an azimuth and an elevation of a target to locate the spatial location of the target by using echoes obtained by two array elements, resolving a problem that two array element antennas cannot locate the space coordinates. In a positioning method based on bionic pinnae of a bat according to filtering characteristics of bat ears, a method for estimating a spatial location by a neural network is used, and a pulse string estimation method is used to reduce the error of estimated angles, to obtain a precise azimuth and elevation.
