deciBel Research has a rich history of developing algorithms to improve radar tracking, discrimination, debris mitigation, track accuracy, and target discrimination. deciBel Research has developed a set of high-fidelity, physics-based modeling and simulation tools. Our toolset provides data manipulation, modeling, simulation, and analysis capabilities for the specific purpose of constructing physics-based representations of threats, sensors, environments, and scenarios and computing the dynamic signatures expected from complex sensor missions and engagements. Our tools are extensively used within our customer base to process and generate large data sets for virtual or hardware in the loop testing. The tools also assist with the processing and analyzes of flight test data and post-flight reconstructions.
