Abstract : General properties of the solutions to transient electromagnetic scattering problems are described. Electromagnetic field waveforms produced by the scattering of transient plane waves from finite objects are related to those produced by an impulsive plane wave. Properties of the impulse response waveforms at great distances from the target, particularly in the backscattering direction, are discussed. Various methods for approximation of impulse response waveforms using time and frequency domain concepts are suggested and illustrated. Other applications of response waveforms to target identification and to prediction of radar echo pulse waveforms are described. (Author)
