Target Imaging From Multiple-Frequency Radar Returns.
Abstract
A new approach to synthetic target image generation from electromagnetic scattering measurements is described and illustrated. Complex harmonic samples of the back-scattered response at ten frequencies lying in the low resonance range of the target response spectrum are used as input data for this approach. A periodic ramp response waveform synthesized from these data is shown to be correlated to the crosssectional area vs distance along the line-of-sight, or profile function, of the targets measured. A technique using profile function data at three orthogonal target look angles for the mathematical specification of a three-dimensional 'approximate limiting surface' is described. Visual images simulating an isometric view of the surface are then constructed. (Author)
