Standard multispectral environment and effects model (STMEEM)

The Joint Modeling And Simulation System (JMASS) is a Modeling and Simulation (M&S) system which provides a software architecture for the development, execution and post-processing of simulations. Additionally, it implements a set of standards by providing tools that assist in development and application of reusable models and model components. The JMASS program is at a critical program milestone where the program will need to serve the M&S needs of more users covering more modeling domains. The vast majority of these M&S interests involve some aspect of digital environmental modeling. Furthermore, virtually every existing simulation with an environmental effects function models only a single electromagnetic domain, such as radio frequency (RF), millimeter wave (M&S), infrared (IR), near visual or visual. The result is a tight coupling of the simulated objects and the specific environmental effects modeled. Decoupling the environment from the user-defined players permits object based modeling of the players which conforms to the JMASS Software Structural Model. The need for a common multispectral environment is to promote user developed model (player) reusability and ensure all electromagnetic representations remain consistent among all players incorporated into a single scenario. The environment propagation effects models should be developed by the individual spectral domain experts in response to the at-large needs of the JMASS user community. The Standard Multispectral Environment Effects Model (STMEEM) program has set out to design and implement a common environmental framework which would provide the capabilities described above. This paper describes the efforts of the STMEEM program to date and discusses the impact a common environmental framework would have on future JMASS users and model developers.
