Phased-MIMO Radar: A Tradeoff Between Phased-Array and MIMO Radars [PDF]

open access: yesIEEE Transactions on Signal Processing, 2010
We propose a new technique for multiple-input multiple-output (MIMO) radar with colocated antennas which we call phased-MIMO radar. The new technique enjoys the advantages of MIMO radar without sacrificing the main advantage of phased-array radar which is the coherent processing gain at the transmitting side. The essence of the proposed technique is to

Spatial information in phased‐array radar [PDF]

open access: yesIET Communications, 2020
In this study, the application of information theory to describe radar measurement problems is investigated. In Shannon's information theory, mutual information is used to quantify the reduction in the a priori uncertainty of the transmitted message.
