John L. McDaniel Enterprises, Inc. (MDE) focus is on Modeling and Simulation. MDE was founded in 1976 by John L. McDaniel to provide engineering in radar low observable technology. This included developing low observable coatings, applying these coatings to various systems, and testing the radar characteristics of the coated systems. MDE also assessed world-wide low observable technology capabilities. In 1987, Bonnie McDaniel joined MDE, bringing knowledge and experience in sensor and BM/C3 algorithm development and advanced data processing techniques. This knowledge was applied to the sensor and materials technology efforts underway in the company to create models of expected performance of various materials. Ms. McDaniel inherited full ownership and direction of MDE in 1989 and changed the focus from radar absorbent materials research to modeling and simulation. MDE performed on the Extended Air Defense Testbed (EADTB) for the U.S. Army Space and Missile Defense Command (USASMDC) under contract to Hughes / Raytheon. MDE was a major player in developing the initial specifications for many of the EADTB algorithms. Subsequently MDE supported the development of the requirements specifications for each delivery, developed models of military systems, and provided technical direction for implementing software to meet the stated requirements. MDE is currently performing advanced modeling and simulation tasks for USASMDC under contract to Maximum Technology Corporation (MTC). For these tasks, MDE is supporting the re-architecting of sophisticated legacy software and is directing system architecture excursion analyses.
