EVALUATION OF CONVOLUTION INTEGRALS OCCURRING IN THE THEORY OF MIXED PATH PROPAGATION
Abstract
The theory of propagation of electromagnetic waves around a sphere treats the sooth homogeneous case, i.e., the case in which the surface impedance of the sphere is uninterrupted by an abrupt change in conductivity such as a lnd/sea boundary. It is known, however, that such a theory can be extended to treat inhomogeneous, irregular terrain by formulating certain convolution integrals which utilize the smooth homogeneous formuas. The evaluation of these integrals can be accomplished with dispatch on a large-scale electronic computer with the aid of numerical analysis techniques. (Author)
