六、内容简介：
Multiple-input multiple-output (MIMO) radar technology, which was introduced about twenty years ago, provides enhanced flexibility in transmit signal design, and since then, many works have been devoted to waveform design in space, time, and frequency. This problem was also extended to cognitive radars, where the transmit signal is sequentially designed based on history observations. Various criteria have been used for waveform design, such as detection or estimation performance. The most popular criteria that have been proposed, are based on the Cramér-Rao bound (CRB), and the Bayesian CRB (BCRB). The popularity of these bounds stems from their simplicity. In this talk, we consider the Bayesian framework and via simple examples it will be shown that the use of BCRB as an optimization criterion leads to absurd waveforms and poor performance. The reasons for this phenomenon will be analyzed and discussed. Two new alternative Bayesian bounds will be presented and implemented for spatial waveform design. The first bound, called AT-BCRB, is a simple modification of the BCRB. Unlike the BCRB, the new bound is asymptotically tight. The second bound is a modification of the Weiss-Weinstein bound (WWB), which is found to be tigher than the WWB, and is related to the ambiguity function. Examples for the use of the proposed bounds for MIMO radar waveform design and antenna selection will be provided.

During 1996–1998 he was with the Department of Electrical and Computer Engineering (ECE), Duke University, Durham, NC, USA, as an Assistant Research Professor. In 1998, he joined the Department of ECE, Ben-Gurion University of the Negev, Beer-Sheva, Israel, and served as the department head during 2017-2019. In May 2019 he established the school of ECE and served as its head till August 2021. He served as an Associate Editor (AE) for IEEE Transactions on Signal Processing during 2001–2004 and 2011–2015, and is currently a Senior Area Editor (SAE) for these transactions. He served as an AE and SAE of IEEE Signal Processing Letters during 2012–2015 and 2015–2018, respectively. He is currently also a Subject Editor for the Elsevier Signal Processing journal. He was a member of the IEEE Sensor Array and Multichannel (SAM) technical committee during 2010-2015 and was the technical program Co-Chair of the IEEE SAM 2010 workshop. During 2015-2021 he served as a member of the Signal Processing for Multisensor Systems (SPMuS) of EURASIP and during 2017-2022 he was a member of IEEE SPTM Technical Committee. He is co-author of 7 award-winning papers in IEEE conferences and workshops. His research interests include estimation and detection theory, learning algorithms, and radar signal processing.
