Multi-Target Radar Imaging Based on Phased-MIMO Technique—Part II: Adaptive Resource Allocation

The advantages of phased-MIMO technique have been utilized for multi-target imaging in the first part of this paper, and the better multi-target imaging performance has been shown compared with the traditional phased-array radar imaging and traditional MIMO radar imaging. For multi-target imaging, the limited radar resources should be allocated for different targets to achieve the maximal performance of radar. By establishing and solving a radar resource allocation optimization model, an adaptive resource allocation strategy for multi-target imaging based on phased-MIMO technique is proposed. With the method, the multi-target imaging efficiency can be improved significantly. The effectiveness of the proposed method is demonstrated by simulations.
