sonar with a cylindrical array. Based on a known spatial spectrum estimation technique, the
method has been successfully used in linear array systems. Its accuracy of bearing is
satisfactory and ensures a relatively low computational effort. The article discusses certain
simplifications and assumptions to adapt the spatial spectrum estimation technique in linear
arrays to the needs of cylindrical arrays. Simulation results are compared to those achieved
in the monopulse method.
