Speaker: Dr. Vito Mecca
Time: 5:30PM, Social – 6:00PM Talk
Location: Lincoln Laboratory Cafeteria
Directions:
From 95/Exit 31B. Take Exit 31B onto Routes 4/225 towards Bedford – Stay in right lane. Use Right Turning Lane (0.3 mile from exit) to access Hartwell Ave. at 1st Traffic Light. Follow Hartwell Ave. to Wood St. (~1.3 miles). Turn Left on to Wood Street and Drive for 0.3 of a mile. Turn Right into MIT Lincoln Lab at the Wood Street Gate. Have a valid driver’s license to present to security. From 95/Exit 30B. Take Exit 30B on to Route 2A – Stay in right lane Turn Right on to Mass. Ave (~ 0.4 miles – opposite Minuteman Tech.). Follow Mass. Ave for ~ 0.4 miles. Turn Left on to Wood Street and Drive for 1.0 mile. Turn Left into MIT Lincoln Lab at the Wood Street Gate Have a valid driver’s license to present to security.
All attendees must present a valid driver’s license to MIT Lincoln Laboratory security. To get to the Cafeteria, proceed toward the Main Entrance of Lincoln Laboratory. Before entering the building, proceed down the stairs located to the left of the Main Entrance. Turn right at the bottom of the stairs and enter the building through the Cafeteria entrance. The Cafeteria is located directly ahead.
Phased array radar systems are a more flexible alternative to traditional single-element dish radar systems. Phased arrays operate by applying a different delay – or phase shift – to signals at each element of the array. This process effectively focuses or ‘steers’ the radar’s spatial beam response and can be performed on both signal transmission and reception. Continuing advances in computational capacity and hardware design have allowed for complete digital reception of multiple, simultaneous beams and subsequent digital processing. However, radar systems capable of simultaneously transmitting multiple different coded waveforms from each transmit element have been unavailable in the past.
This talk introduces a class of Multiple-Input Multiple-Output (MIMO) radars which are capable of emitting different signals from each transmitter element. In this introductory-level talk, the
fundamental concepts behind phased array and MIMO radar techniques are explained in terms of real-world scenarios where MIMO operation would be advantageous. The advanced MIMO techniques developed at Lincoln Laboratory for joint transmit and receive array processing are presented in conjunction with data results.
Dr. Vito F. Mecca is a member of the Technical Staff in the Advanced Sensor Systems and Test Beds group in the Air and Missile Defense division at MIT Lincoln Laboratory. He holds B.S.E., M.S., and Ph. D. in the field of Electrical and Computer Engineering from Duke University in Durham, North Carolina. Vito’s research interests include adaptive signal processing, phased array processing, detection and estimation theory, and Multiple-Input Multiple-Output (MIMO) radar techniques with applications to high frequency over-the-horizon radar systems and the ionospheric space environment. Vito has led many high frequency radar and ionospheric experimental measurement campaigns in the U.S. and has participated in several experiments with colleagues from around the globe. He has been a member of IEEE since 2004 and is an active lecturer for various topics in the MIT Lincoln Laboratory introductory radar courses.
