Modeling and Simulation Technologies for Multi-Sensor Dynamic Targeting

Under sponsorship from the Sensors Directorate at AFRL, HyPerComp has significantly advanced the state of the art of time-domain, broad band electromagnetic simulations. The TEMPUS (Time-Domain ElectroMagnetic Parallel Unstructured Simulator) environment is a self contained code suite that includes computer aided design (CAD) geometry creation and repair, unstructured gridding for full-scale targets with general materials, scalable parallel code architecture, higher-order accurate discontinuous Galerkin solvers for Maxwell's equations, and post processing utilities for solution visualization and extraction of final results like bistatic and monostatic radar cross section (RCS), synthetic aperture radar (SAR) images, and high-range-resolution (HRR) profiles. TEMPUS is fast maturing to provide accurate solutions to all aspects of physics-based phenomenological scattering features. In view of the current demonstrated capabilities of TEMPUS and its planned role as a full wave solution-based critical electromagnetics technology for DoD, HyPerComp proposes a Phase II activity to continue development of TEMPUS in four major areas: 1)Improve the functionality of current TEMPUS to make it reliable and user friendly, 2) optimize the implementation of some of the existing modules and perform further validation, 3) formulate and implement new capabilities within TEMPUS, and 4) direct support to AFRL in the installation and application of TEMPUS.
