Scattering of an FM Signal From an Array of Spheres
Abstract
This document describes the investigation of the dependence of peak target strength on source bandwidth and scatterer spacing using arrays of rigid scatterers and LFM signals at 200-, 400-, and 800-Hz bandwidths. The results demonstrate that, as the bandwidth increases, the average peak target strength increases and shows less aspect dependence (except near 90 degrees) due to more opportunity for coherent addition of the scattering amplitudes. As the spacing between the scatterers was increased, there were more fluctuations in aspect angle due to the greater directivity of the scattering pattern. Misaligning scatterers in a regularly spaced array smoothed the overall response and increased the average peak target strength.
