Radar Coincidence Imaging With Random Microwave Source

The radar coincidence imaging (RCI), as a novel radar imaging method, is presented in this letter. Firstly, the relationship between the deployment of general random microwave array source and the resolution of RCI under second-order correlation methods (SOCM) is presented. Then, the super-resolution RCI is obtained assisted by optimization algorithms based on the matrix form of measurement data. Finally, the mirror phenomenon of RCI, which is caused by the spacing of radar elements, is presented. In experiments, we form RCI using uniform 1-D antenna array with random phase and random amplitude modulated excitation signal for each radar element. The proposed analysis is validated through numerical simulations and experiments.
