Abstract
En 中文
A novel generic two dimensional (2D) sparse multiple-input-multiple (MIMO) topology is proposed. Based on this topology, a real-time, compact demonstrator is realized at millimeter-wave range with narrow frequency band. It shows that the topology reduces hardware effort. Theoretical and experimental studies of focusing characteristics of the demonstrator are performed. These studies demonstrate that the proposed topology provides comparable focusing capabilities to another novel topology such as curvilinear configuration. Imaging capability of the proposed array is experimentally demonstrated. It is shown that the demonstrator is favorable to be employed on mobile platforms for fast and accurate imaging.
