Аннотация:The problem of diffraction of ultrasonic waves by a sharp-angled rigid cone is studied. In the framework of the parabolic equation method, an analytical solution of the problem with an arbitrarily located point source is constructed. Namely, the problem is reduced to the Volterra boundary integral equation, which can be solved using the Fourier transform. An experimental measurement of the diffracted field is performed. The experiment is based on the M-sequence method adapted for narrowband sound sources. The experimental and theoretical results are compared.
