Space-Time Adaptive Processing for Heterogeneous Radar Clutter Scenarios
Dr. Muralidhar Rangaswamy, Air Force Research Laboratory Sensors Directorate
Early contributions of Howells, Applebaum, and Widrow on adaptive arrays will be briefly reviewed. Sample Matrix Inversion (SMI) method and its variants from the standpoint of CFAR and training data support for covariance matrix estimation will be presented. Candidate reduced-dimension methods will be introduced. Problems encountered in covariance estimation on account of heterogeneous training data and ameliorating solutions from phenomenological, systems and statistical perspective and resulting impact on STAP algorithm performance will be featured. Statistical and ad-hoc techniques for characterizing heterogeneous training data will be discussed. The resulting impact on STAP performance will be presented using simulated and measured data. Some attention will be devoted to recent advances from knowledge based STAP.
Muralidhar Rangaswamy received the Ph.D. degree in electrical engineering from Syracuse University, Syracuse, NY, in 1992.
He is presently a Senior Electronics Engineer at the Sensors Directorate of the Air Force Research Laboratory (AFRL), Hanscom Air Force Base, MA. Prior to this, he has held industrial and academic appointments. His research interests include radar signal processing, spectrum estimation, modeling non-Gaussian interference phenomena, and statistical communication theory. He has co-authored more than 70 refereed journal and conference record papers in the areas of his research interests. Additionally, he is a contributor to three books and is a co-inventor on two U.S. patents.
Dr. Rangaswamy received the 2004 Fred Nathanson Memorial Radar Award from the IEEE Aerospace and Electronics Systems Society, the 2006 Distinguished Member award from the IEEE Boston Section, and the 2005 Charles Ryan Basic Research Award from the Sensors Directorate of AFRL, in addition to 20 AFRL scientific achievement awards.
Directions to MIT Lincoln Laboratory:
The meeting will be held at the MIT Lincoln Laboratory Cafeteria in Lexington, MA. Refreshments will be served at 5:30; the talk will begin at 6:00 pm. The talk is open to the general public. Dinner at a local restaurant will follow for all those interested in continuing conversations with the speaker.
Directions to Lincoln Laboratory Cafeteria from points north: Take I-95/128 south to exit 31B, Routes 4 & 225 towards Bedford. Stay in right lane and use the right turning lane (0.3 miles) to access Hartwell Ave at first traffic light. Follow Hartwell Ave to the end; take a left onto Wood Street (just before the AFB gate). Lincoln Laboratory entrance is 0.5 miles on right. The entrance to the cafeteria is on the lower level left of the main entrance.
From points south: Take I-95/128 north to exit 30B, Route 2A west. Turn right on to Mass Ave (~0.4 miles). Turn left on to Wood Street (~0.4 miles) Lincoln Laboratory Wood Street entrance is 1 mile on left. The entrance to the cafeteria is on the lower level to the left of the main entrance.
