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 seminar introduces a class of multiple-input multiple-output (MIMO) radars that are capable of emitting different signals from each transmitter element. In this introductory-level seminar, the fundamental concepts behind phased-array and MIMO radar techniques are explained in terms of real-world scenarios in which MIMO operation would be advantageous. The advanced MIMO techniques developed at MIT 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 Advanced Sensor Systems and Test Beds group in the Air and Missile Defense division at MIT Lincoln Laboratory. He earned the Bachelors of Science in Engineering (2004), Master of Science (2006), and Doctor of Philosophy (2008) degrees at Duke University in Durham, North Carolina. Since joining MIT Lincoln Laboratory, Vito has had led multiple high-frequency radar and ionospheric experimental campaigns both within the U.S. and abroad. His research interests include novel adaptive signal processing, phased array processing, and Multiple-Input Multiple-Output radar techniques with applications for the development of next-generation, high frequency over-the-horizon radar systems.
