Calculation of amplitude-phase characteristics of signal scattered obliquely on meteor trail

Diffraction processes occurring during oblique incidence of a plane radio wave on a cylinder with an irregular radius are investigated for the case of the decaying of a meteor trail. The boundary problem for the differential equation of the functions of the radial coordinate is found and solved by reduction to a Cauchy problem. Expressions are derived for the amplitudes and phases of the reflection H- and E-waves in a cylindrical coordinate system. The behavior of the amplitude and phase of the reflected waves with both polarizations are investigated as a function of the angles theta, phi and the normalized radius. It is found that a rigorous solution of the wave equations for oblique incidence makes it possible to calculate the characteristics of the reflected signal more accurately than by the approximate method.
