Abstract

Interest in signature phenomenology studies has increased steadily in the past several years. These studies are intended to support analysis into the advantages of increasing radar bandwidths for both stationary and moving target applications. Because measured data is often limited it is common to augment data with stepped frequency data from turn-table collections, compact range collections, or generated synthetically with products like XPatch. Airborne systems frequently employ linear frequency modulated (LFM) radars. The corresponding frequency response of the target is typically obtained with a de-chirp on receive process. The effects of this processing are well understood for point source scatterers; however, the effects have not been thoroughly analyzed for more general types of scatterers. Little attention has been placed on the effects of de-chirp on receive processing for moving targets. Previously the authors have derived the relationship between stepped frequency and LFM radar measurements for general stationary objects. Distortions are seldom apparent in images produced by these radars, but can be important for wideband measurements, particularly when resonant scattering mechanisms exist In this paper the authors extend results to the moving target case.
