Abstract : The paper considers a propagation model where a signal is propagated via M paths with each component arriving on a horizontal plane from different directions. The M components have random phases, but are coherent with each other. An expression, in the form of a polynomial of complex terms, is derived for the total field strength over the site. By multiplying this polynomical by another with identical but conjugate terms, a polynomial of real terms is obtained; it represents the field intensity distribution and consists of a constant term plus a series of sinusoidal periodicities.
