L'insegnamento di "Multichannel Signal Processing" ha come obiettivo quello di fornire agli studenti le conoscenze fondamentali relative aiall'elaborazione del segnale multicanale e relative applicazioni in campo radar. Prendendo le mosse dai metodi avanzati di stima spettrale (i metodi di base sono già stati visti nel modulo di Statistical Signal Processing) le lezioni preseguono con una dettagliata analisi delle tecniche più comuni di array processing. Nelle ultime 20 ore di lezione gli studenti vedranno alcune applicazioni di tecniche multicanale a sistemi radar STAP, bistatici passivi e MIMO. Le lezioni teoriche sono sempre complementate da esercitazioni in Matlab.
The course of "Multichannel Signal Processing" aims to provide students with the fundamental knowledge related to multichannel signal processing and related applications in the radar field. Starting from the advanced methods of spectral estimation (the basic methods have already been seen in the Statistical Signal Processing module) the lessons continue with a detailed analysis of the most common techniques of array processing. In the last 20 hours of lessons, students will see some applications of multichannel techniques to STAP, passive bistatic and MIMO radar systems. Theoretical lessons are always complemented by exercises in Matlab.
