Abstract

Spatial reconstruction of a rigid, moving target's scattering centers using one dimensional, high range resolution (HRR) radar remains of high interest to synthetic aperture radar (SAR) processing of moving targets. Innovative range and Doppler equations for a rotating target with constant angular velocity were developed by Fazio, Hong, and Wood and presented at the April 2002 SPIE AeroSense Conference in Orlando, Florida. Further research has produced a method of reconstructing a three-dimensional scattering center model of a moving target with variable angular velocity. The reconstruction algorithm uses the relative ranges from a minimum of five observations of three scattering centers. In-plane rotational motion provides necessary information for positioning the projection of the scattering centers onto the observation (reconstruction) plane; while out-of-rotational-plane target motion is necessary to locate the center above or below the reconstruction plane.
