Broad Band Inverse Scattering.
Abstract
The extraction of target characteristics from the broad band, impulse-generated echo at a single target aspect is demonstrated for spherical and spheroidal targets. Target recognition by broad band echo-ranging is further compared with CW echo-ranging on theoretical and operational grounds. Even though impulse echo-ranging offers certain advantages, inverse scattering calculations do not appear practical except at short range, and in the absence of overlapping direct and surface-reflected returns. A promising application of broad band echo-ranging not related to inverse scattering proper appears to be the determination of a target's structural characteristics through shock wave excitation of its structural resonances.
