V.T.Matsypura, L.A.Trunova A wedge-shaped acoustic antenna |
Acoustic bulletin, Vol. 16 ¹ 2, (2013-2014) |
| The paper deals with considering of a plane problem on interaction of a group of point sources with a wedge-shaped reflector. The near and far fields are studied depending on the wedge geometry and location of the sources. The possibility of rational choice of the amplitude-phase distribution of sources' excitation for improving of the antenna's radiative characteristics is shown. The features of radiation of the narrow-band pulse by the wedge-shaped antenna are investigated. |
