Abstract
One solution of the problem of detection of leakage on underwater pipe lines is the creation of a system of visualization of the signal source of acoustic emission. Such a system contains two linear orthogonally oriented antenna arrays (AA), each of which provides sector scanning in a longitudinal plane. The author considers the resolving power of one of such array. Resolving power is the capacity of any detection system to fix separately two closely arranged objects. The determining factor in an estimation of resolving power is width of the direction diagram. The author conducts analytical research of the given parameter for a linear equidistant AA consisting of round converters, with allowance for a processing algorithm of partial signals. Thus, calculation is carried out for a zone of Fraunhofer diffraction.
