The article presents a method for improving the accuracy of bearing in multibeam sonar with a cylindrical array. The antenna’s non-linearshape and the resulting non-uniform sampling of the signal in space, mean that known methods of high-resolution spectral analysis cannot be used. In order to apply an algorithm from this group, a linear virtual antenna must be produced. The paper presents a technique of mapping a cylindrical array to the equivalent linear form. The simulation results present the accuracy of bearing estimation in the presence of white noise. Furthermore, the limitations of the method and practical aspects of the application in a real sonar system are discussed.
