Abstract

Spectral Sciences, Inc., and subcontractors Corvid Technologies, Inc., and Busek Co., Inc. propose a Database-Driven Discrete Debris Signature Model (4DSM) for signature estimates of discrete post-intercept debris (PID) and solid-rocket motor (SRM) debris. The 4DSM software tool is designed to post-process first-principles code (FPC) outputs. The tool will use a validated debris-properties database and an innovative method to harness the database to generate signatures. The key innovation is a new, fast parametric model in 4DSM that relates discrete debris signature properties to their formation conditions. In Phase II, the database will be constructed through a systematic series of measurements on debris collected from ground tests. The database will be used to train the parametric signature model, and, where appropriate, will be directly integrated into a signature model using an interpolative scheme. The 4DSM software will be tested and validated against ground and flight test field data. Phase III will transition this fast running post-processing tool to missile defense simulation architectures.
