Antenna Selection and Placement Analysis of MIMO Radar Networks for Target Localization
International Journal of Distributed Sensor Networks, 2014 A distributed MIMO radar network consists of a large number of transmitters/receivers to cover a sensing area of interest but under the constraint that the number of antennas is limited. The problem of selecting a subset of antennas at a sampling time to
