Abstract

In this chapter, the numerical procedures to calculate the transient scattering from perfectly conducting, arbitrarily shaped, three-dimensional finite-sized bodies are discussed. There are many practical applications to treat such bodies; many systems are employing short-pulse radar systems. These systems are being used for target identification, high-range resolution, and wideband digital communications. In all these situations, the structures involved are finite-sized bodies. Also, numerous military and space applications often involve the calculation of radar signatures of complex bodies over a wide frequency range that can be easily accomplished by the techniques discussed. Although, the chapter presents numerical examples for standard canonical shapes only, the techniques are general and can be used for a wide variety of geometrical shapes. We first develop the basic integral equations to obtain the transient scattered field.
