Collaboratively-working Multi - MIMO Radar: Approach and Hardware Implementation

For multiple input multiple output (MIMO) radar, the angle resolution cannot be changed after designed and manufactured. To solve this problem, this paper proposes a scheme of combining multiple radio frequency (RF) boards, which can quickly improve the angle resolution of MIMO radar without expensive cost of resuming production. The combined radar system model and aperture synthesis method are analyzed, and a hardware system including functional modules such as RF boards, data capture boards and signal processing boards is designed to implement this scheme. Experiment and real data processing results are presented to demonstrate the effectiveness of the proposed method and hardware implementation.
