This text brings together for the first time the results of previously published research papers and technical reports on the subject of obtaining improved precision for radar target signature modeling and target-motion solutions. It provides an analysis framework that incorporates a new class of signal and data processing techniques capable of extracting a high level of detail characterizing the target radar signature. The performance of the new approach exceeds that of conventional Fourier-based processing techniques. The enhanced performance provided by the new framework is made possible by recent advances in radar signal processing technology. The material is drawn from research dedicated to developing high-fidelity signature models of targets that are difficult to model, either because they are very complicated and standard computational codes cannot be applied, or because the data comes from field tests using the target where the motion parameters are unknown and must be estimated. The techniques extract target scattering center locations and their associated diffraction coefficient behavior and integrate the scattering center model into a fast-running signature generation code. The framework assumes that the radar data are recorded and processed collectively to achieve a comprehensive signature model of the target.
