Abstract

Frequency spectrum of the wave scattered by randomly rough surface back to transceiver located on aerospace vehicle moving towards the surface is evaluated and investigated in explicit form. Kirchhoff’s (physical optics) method is applied for scattered field evaluation. It is assumed that transceiver irradiates directive spherical wave illuminating circled area on the surface. Distribution of the rough surface height is assumed to be normal with isotropic Gaussian correlation function. Application the effective approximation formula for characteristic functions difference in integrand gives rise to spectrum evaluation for arbitrary height of surface irregularities. Frequency spectrum is shown to exist in two forms. The first one is represented by monotonic curve, depending on correlation distance of the rough surface. The second form includes one maximum, which position and amplitude are related with the roughness’ mean square slope. On the parameter plane the curve is plotted which separates regions with abovementioned spectrum forms.
