Dr. T.N. Truong of the University of Utah is a member of the technical team working on this program.
	April 2006	PST completed a program with Victor Technology, funded by the Air Force Research Laboratory to develop a "Handbook for Rocket Plume RF Attenuation Predictions".
	April 2006	Awarded a Phase I SBIR funded by MDA entitled "Plume Simulation Using Advanced Image Processing Techniques".  PST worked with Combustion Research and Flow Technology, Inc. on this effort.
	February 2005	Awarded a Phase I SBIR funded by MDA entitle "Low Altitude Plume Chemistry Signature Modeling" PST worked with Dr. T.N.Truong, University of Utah on this effort.
	February 2005	Awarded a Phase I SBIR funded by MDA entitled "Integration of Thermal Management Systems and Quasi 3-D Modeling with Plume Signature Analysis".  This program explored the feasibility of coupling an engineering level thermal design tool, VITMAC (Vehicle Integrated Thermal Management Analysis Code) with a Quasi 3-D enhanced Standardized Plume Flowfield Model, SPF-IIIQ3D. PST worked with Science Applications, Inc. on this effort.
	December 2004	PST initiated work to support threat characterization database development at AEDC in coordination with DIA/MSIC.
	October 2004	PST is funded by Lockheed Martin Maritime Systems for technical services for ESD (Engagement Sequence Definition) Plume RF Analysis in support of the Aegis Ballistic Missile Defense Program..
	September 2004	Awarded a Phase II SBIR funded by the Air Force (AEDC) entitled "Computational Toolkit for Generating Missile Signature Databases". PST worked with Opto-Knowledge Systems Inc. (OKSI) to develop two powerful computational methodologies for fusing missile plume model predictions with sensor measurements to produce highly accurate missile signature databases. The first methodology, A-SCOPE (Automatic Simultaneous Constraint Optimization for Parameter Extraction) automatically extracts optimal inputs to the government standard plume signature prediction codes that: (1) are physically realistic within their known covariance, and (2) produce signatures that are the most consistent with sensor measurements.  The second methodology, MODEX (Model Extrapolation) compares plume signature predictions and sensor measurements to derive extrapolation factors, which anchor the predictions to the data. These factors are then used at off-measurement conditions to create a database of signatures at all possible viewing conditions, flight parameters and spectral regions.
	August 2004	Awarded a Phase II SBIR funded by MDA entitled "Missile Plume Radar Attenuation and Cross Section".  PST worked with Sutton and Company, Inc. and Victor Technology to develop computational tools to predict RF interactions (attenuation, diffraction, reflection, Doppler and backscatter) with missile exhaust plumes.
	August 2004	PST is funded by Ball Aerospace & Technologies, Inc on an "Early Launch Detection Simulation" program to determine the ability of plume signature predictive methodology to simulate flight IR/Visible signatures via comparisons between signature predictions and recent data collections by an advanced multi-spectral sensor.
