Abstract
We consider scattering of a pulsed narrow wave beam on a rough surface with a locally-specular indicatrix. Analytical expressions for the average received power are obtained for normal distributions of heights and slopes of the rough surface in two cases in which the direction to the receiver is close to or strongly different from the direction of specular reflection. It is shown that in these cases, the received echo pulses have drastically different profiles determined by the source and receiver parameters, the scheme of sounding, and the variance of the heights and slopes of the rough surface. The obtained analytical expressions for the average received power agree well with the results of numerical simulations.
