The ability to make radar signature databases portable for use within similar sensor systems is critical to the affordability of airborne signature exploitation systems. The capability to hybridize measured and synthetic signature database components as well as integrate signature components from different radar sensors will maximize the investment required to build complex radar signature databases. Radar target scattering response signatures are analyzed as random processes. Radar signature analysis techniques using information theory are introduced. Methods for using the target scattering response signal subspace within limited aspect viewing sectors are developed.

Research in the area of air-to-ground target detection, track and identification (ID) requires the development of target signal models for known geometric shapes moving in ground clutter. Space-time adaptive filtering techniques in particular make good use of temporal-spatial synthetic radar signal return data. A radar signal model is developed to generate synthetic wideband radar signal data for use in multi-channel adaptive signal processing.
