1.1 INTRODUCTION
MIMO radar is an emerging technology that is attracting the attention of researchers
and practitioners alike. Unlike a standard phased-array radar, which transmits scaled
versions of a single waveform, a MIMO radar system can transmit via its antennas
multiple probing signals that may be chosen quite freely (see Fig. 1.1). This waveform
diversity enables superior capabilities compared with a standard phased-array
radar. In Refs. 1-4, for example, the diversity offered by widely separated
transmit/receive antenna elements was exploited. Many other papers, including,
for instance, Refs. 5-29, have considered the merits of a MIMO radar system with
collocated antennas. The advantages of a MIMO radar system with both collocated
and widely separated antenna elements are investigated in Ref. 30.
For collocated transmit and receive antennas, the ... read full excerpt from MIMO Radar Signal Processing ebook
