Influence of reflector edges diffraction on manifestation of backscatter amplification effect

摘要

Abstract: It is shown that in a regime of weak turbulence the edge diffraction on a reflector has a profound effect on intensity distribution of the reflected wave and on the manifestation of backscatter amplification. Therewith the dependence of the amplification factor on the Fresnel number of the reflector radius has an oscillating nature both for the corner reflector and for the plane mirror one. In going from a weak turbulence regime to a strong one the effect of diffraction on reflector edges on backscatter enhancement becomes negligible. !21
