JCAMS Presents Dr. Robert McMillan on Radar

Joint Communications, Antennas & Propagations, and Microwave Theory and Techniques Society (JCAMS)

“A Probabilistic Model of the Radar Signal-to-Clutter and Noise Ratio”

Thursday December 10, 2009 at 11:15 am

Speaker: Dr. Robert McMillan

Meeting Location: ADTRAN Inc. Executive Cafeteria

The Huntsville chapter of the IEEE Joint Communications, Antennas & Propagations, and Microwave Theory and Techniques Society (JCAMS) invite you to attend a technical meeting on December 10, 2009. The program will begin at 11:15 am Dr. McMillan’s presentation beginning at approximately 11:45 am and end about 1:00 pm.

Synopsis:
Four effects relevant to the determination of the ratio of radar signal to clutter and noise are considered. These effects are atmospheric turbulence, target fluctuations based on the Swirling models, zero-mean Gaussian background and receiver noise, and lognormal-distributed clutter. Radar return signal levels are affected by target fluctuations and atmospheric turbulence, characterized by a variant of the Rayleigh distribution and a lognormal distribution, respectively. Since these distributions are not independent and identically distributed (IID), they cannot be simply added, and must be treated by combining them in a manner similar to convolution. Also, clutter and noise are not IID, and must be combined in a similar way. The ratio of these two combinations comprises a probabilistic model of the ratio of radar signal to clutter and noise. This ratio is the probability that a given signal level will be achieved in the presence of atmospheric and target scintillations divided by the probability that a given clutter and noise level will be observed. To determine the ratio of the actual signal to clutter and noise, we must multiply these probabilities by the mean powers in these phenomena, as will be shown later. Several cases of interest were treated by varying the average radar cross section, the log intensity standard deviation of turbulence, the radar threshold-to-noise and signal-to-noise ratios, and the distributions of lognormal clutter.

The presentations are open to anyone interested in the topic: IEEE membership is not required to attend.

Seating is limited, so please RSVP by email to Eric Grigorian at as soon as you can, but no later than close of business December 8, 2009 if you want to attend.

I hope to see you there!

Huntsville EMC Wins Prestigious Award

Congratulations to the IEEE Electromagnetic Compatibility (EMC) Huntsville Chapter! They have been selected from among all EMC chapters worldwide as the recipient of the Most Improved Chapter Award from the international IEEE EMC Society. This award signifies outstanding improvement in membership services and establishing goodwill for the EMC Society. It was presented to the EMC Huntsville Society Chair, Doug Parker, at the International EMC Symposium in Austin, Texas in August of this year.

Under the leadership of Doug and many other local volunteers, the Huntsville EMC Chapter has made a huge impact in the local technical community. Each year, they host frequent technical meetings that are free of charge and open to everyone in the community. EMC brings renowned IEEE Distinguished Lecturers to share their technical knowledge in training sessions and hosts a bi-annual tabletop event that links industry, academia and professionals in the EMC discipline.

Our EMC Society also supports other local organizations and events. This year, they reached out to engineering students by supporting IEEE UAH Student Branch events, speaking to the UAH engineering students, and purchasing EMC technical books as a donation to the UAH library. They donated heavily to the HATS STEDTRAIN grant, a program that links local K-12 school projects with much needed funding. They also co-sponsored the IEEE 125th Anniversary Celebration at the United States Space and Rocket Center.

The IEEE Huntsville EMC Society was chartered in 2006, and under the care of its first Chair, Glenn Shelby, it has consistently provided outstanding technical events to the community. Through the past several years, the EMC Society has continued to gain momentum. Let’s all congratulate Doug and the other volunteers Huntsville’s IEEE EMC Society on this lucrative award.

Chair's Corner

It has been longer than usual since our last LiveWire article, and we have lots of news to report. First, I invite all of our local IEEE members to join our IEEE Huntsville Section LinkedIn group. The group has been growing steadily since it was created by Past Chair Dr. Belur Dasarathy in December 2008. This is a great way to stay in touch with other members in the area, and to learn about upcoming events and opportunities to participate in our events.

We welcome Ed Worley to the Huntsville Section. Ed is an IEEE Life Member and former Programs Chair from Fort Worth, Texas. We hope that you find Huntsville a great place and help us make it better. On May 12^th and 13^th, the NASA ARMY Systems and Software Engineering Forum was hosted at Marshall Space Flight Center. This free conference was sponsored in part by the IEEE Computer Society. Bob Robinson was instrumental in providing support for this event on behalf of the Section.

May 16^th was the 125^th anniversary of IEEE, and the IEEE Huntsville Section celebrated with a free robotics demonstration at the U.S. Space and Rocket Center. If you missed this event, be sure to catch up by reading the news article. Those of you who were able to attend got a chance to meet many of our volunteers, who facilitated this event. Thanks to Tommy McGuire, Doug Parker, Bob Robinson, Keith Jadus, John Grimm, Renee Coulter, Ed Worley, Eric Grigorian and Frank Parris, all of whom assisted at this event. And special thanks to the IEEE EMC Society, who made a very generous financial contribution to this event.

On May 21^st, the EMC Society hosted a technical lecture by Dr. Michael Hopkins, on the subject of ESD susceptibility and scanning. The EMC Society is one of our most active technical societies. Be sure to review Doug Parker’s summaries of their recent activities. In May the Control Systems Society also hosted a technical lecture, check out Wayne Kendrick’s meeting summary.

The annual Professional of the Year Banquet, hosted by the Huntsville Association of Technical Societies (HATS) was celebrated on June 11^th. This year, the IEEE Huntsville Section awarded this honor to Dr. Bill Seidler of The Boeing Company. Congratulations to Bill on this great accomplishment. Will Preussel, the Chair of our Awards Committee, along with Woody Williams, collected nominations and worked with the Awards Committee to select Dr. Seidler as this year’s honoree.

Tennessee Valley BEST is coming up this fall. We will be looking for volunteers to act as mentors to the competing students, and to assist with the event itself. This is an opportunity to share your knowledge and inspire some young minds! I hope to see you at some of our upcoming events. And thanks to all of our volunteers who have helped out these past few months. We have done some great work! Thank you all.
