Abstract:

Research was concerned with 1 the development of scatter-signal measuring equipment capable of recording bistatic phase and amplitude information as a function of target aspect, and 2 the study, theoretically and experimentally, of methods of synthesizing targets to exhibit precribed scattering properties. It was shown by representative examples that the far-field scattered waveform for short-pulse excitation of scatterers is relatively simple in form and can be related to geometrical and constitutive parameters of the scatterer. It also appears that a reasonable approximation to the response to impulsive plane-wave excitation can be obtained by superposition of scattering values at a number of equally spaced harmonic frequencies. If existing solutions or experimental data for additional scatterers are presented in this form, it should be possible to develop simple rules for predicting the waveform quite generally. Author
