Abstract
Scattering of SODAR signal from a thin rough circular bodies is studied using an integral equation method. The relation between Incident and scattered fields governs by the transition matrix (T-matrix). T matrix has determined using an Integral representation of the Helmholtz equation. The prototype rough surfaces are modeled by a superposition of a number of the sinusoidal surface that are randomly translated and rotated with respect to each other. Numerical results for the scattered fields are presented in the case of an incident plane wave only. For scattered wave are going to discussed the further paper. The conclusion has made here that the amplitude of the backscattered wave is not only dependent on parameters like signal frequency, incident angle and surface characteristics like rms height and correlation function. It’s also concluded that the exact geometry of rough objects is also important for scattering properties, which Implies that a statistical approach to the problem is of limited values. All these mathematical algorithms and plots have developed in the Matlab scientific software.
