讲座题目：On the Design of Multi-Spectrally Constrained Constant Modulus Radar Signals

主讲人：Prof. Augusto Aubry (Italy), Associate professor, IEEE Senior Member, Department of Information engineering

报告简介：The synthesis of constant modulus waveforms that optimize radar performance while satisfying multiple spectral compatibility constraints is considered in this work. For each shared band, a precise control is imposed on the injected interference energy. Furthermore, the compliance with amplifiers operating in saturation is ensured at the design stage where phase-only waveforms are considered. To tackle the resulting NP-hard optimization problem, an iterative procedure based on the coordinate descent method is introduced. The overall computational burden of the algorithm is linear with respect to the code length as well as the number of iterations and less then cubic with reference to the number of spectral constraints. Hence, some case studies are illustrated to highlight the effectiveness of the technique.

主讲人简介：Augusto Aubry received the Dr. Eng. degree (with Honors) and the Ph.D. degree in information engineering, both from the University of Naples Federico II, Naples, Italy, in 2007 and 2011, respectively. From February to April 2012, he was a Visiting Researcher with the Hong Kong Baptist University, Hong Kong. He is currently under research agreement with the Department of Electrical and Information Technology Engineering, University of Naples Federico II, Naples, Italy. His research interests include statistical signal processing and optimization theory, with emphasis on MIMO communications and radar signal processing. Dr. Aubry is the co-recipient of the Best Paper Awards (entitled to B. Carlton) of the IEEE TRANSACTIONS ON AEROSPACE AND ELECTRONIC SYSTEMS with the contribution “Knowledge-Aided (Potentially Cognitive) Transmit Signal and Receive Filter Design in Signal-Dependent Clutter”.
