The Mercer Engineering Research Center (MERC) will be participating in the 32nd annual Dixie Crow Symposium this year. The symposium will be held March 18-22, 2007 at the Museum of Aviation, Warner Robins, GA. Our own Tracy Tillman, Electronics Systems Division Manager, is the Dixie Crow Symposium chair. The Dixie Crow is a chapter of the Association of Old Crows (AOC) which promotes the exchange of new ideas and information and the dissemination of new research and knowledge in the fields of Electronic Warfare and Information Operations.

The name “Old Crows” emerged from the first large-scale use of Electronic Warfare during the WWII Battle of Britain and the U.S. and allied bombing raids over Europe. The Allied Radar Countermeasure operators used the code name “Ravens” and employed receivers and transmitters to monitor and jam threat frequencies. Military jargon later changed “Ravens” to “Crows.” This presentation will review the fundamentals of heat transfer mechanisms applicable to electronic systems. These include heat generation in electronic components, thermal conduction through the components and boards, and convection of heat to the surrounding air. Examples will be presented varying from simple cases that explain concepts, to detailed analyses of circuit boards. Presented by Dr. Robert McGinty Fundamentals of Thermal Analysis with Applications to Electronic Circuits This presentation will discuss how the Multi-System Electronic Warfare (EW) Reprogramming Integrated Suite (MERITS) is being used to support Air Force EW system mission data design and generation requirements, including MERITS background information and the current state of the new PC based MERITS. It will then discuss new functionality being added that provides MERITS with Master Threat Database (MTD) capability in support of multiple EW systems to support the development and maintenance of versioned EW threat, Electronic Order of Battle (EOB), and Intelligence assessment data organized by Areas of Responsibility (AOR) and/or Country. Presented by George DePuy Multi-System Electronic Warfare (EW) Reprogramming Integrated Suite (MERITS The NDEED algorithm was developed to aid in the classification of data where one class has very few samples compared to a second class with many samples. NDEED identifies the smaller class by attempting to wrap ellipsoids around the data in N-dimensional space. The number of ellipsoids is determined through Artificial Intelligence (AI) methods while the ellipsoid "wrapping" algorithm may be performed by either AI or recently developed convex optimization methods. Presented by Steven Boswell NDEED: N-Dimensional Ellipsoid Encapsulation Discriminator Aircraft motion induces the familiar modulation known as the Doppler shift in the carrier frequency of CW and pulsed emitters, as well as, the time of arrival of pulses of pulsed emitters. Another type, Rotational Doppler, is generated by the rotational motion of baselines formed between two (or more) receiving antennas. This presentation presents the history of the robust passive geolocation technology through the 2006 HITL evaluation of the algorithm for the U.S. Navy. Presented by Peter Bryant Rotational Doppler – A Micro-Doppler Technique for Single or Multi-Ship Geolocation This year’s theme of "Reach Back - Push Forward (Using History to Guide the Future)" sets the stage for three MERC briefings, and one short course. They are:
