ABSTRACT

Radar information gathering on numerous objects of interest by means of full-scale and physical experiments involves considerable amount of expense in the form of materials, time, and management. This chapter presents the method developed by the authors for computing scattering characteristics of airborne objects having complex shape and nonperfectly reflecting surface. It considers the method for approximating the smoothed impulse response (IR) of the object given definite spectrum range of illumination signal. The method is applicable for computing impulse responses (high-resolution range profiles) for various radar objects. The chapter describes the scattering simulation method is proposed that accounts for the presence of surface fractures. It proposes when actual computation of scattering characteristics is carried out, the smooth fractions of the complex-shaped object surface are split into triangular facets in order to implement the computation method.
