EXPLOITING SPATIAL DIVERSITY IN MIMO AND MASSIVE MIMO RADAR SYSTEMS
Abstract
The concepts of spatial diversity and of multiple-input multiple-output (MIMO) radars are not certainly new. The idea of MIMO radars has been borrowed by the wireless communication area, where the MIMO technology has been already incorporated into wireless broadband standards like LTE and Wi-Fi, and introduced in the radar community by the seminal paper [Fis06] where the authors evaluate the spatial diversity gain of a MIMO system with M transmitters and N receivers in terms of Signal-to-Noise (SNR) gain, compared to phased arrays. From then on, a plethora of journal and conference papers has been published on the topic and now the first MIMO radars are already in the realization/implementation phase. Still many problems are open and new ideas andtechniques could be associated to spatial diversity in order to improve MIMO radar performances and solve some of the open issues.The goal of this project is to attack some of the open problems proposing new solutions and techniques for, in particular, jammer suppression and MIMO target detection in non-Gaussian environment. We will study as well the possible advantages of largely increasing the number of transmit-receive antennas going from MIMO to massive MIMO radars, as already proposed in the communication 5G standard.
