Compared to conventional 3D radar systems, 4D radar systems require higher angular resolution in both azimuth and elevation. Besides, sparse arrays offer several advantages, including reduced mutual coupling, lower complexity, and high cost-effectiveness, in the radar system design. Furthermore, the multiple-input multiple-output (MIMO) array can theoretically be equivalent to a larger virtual arr...Show More
Multiple-input multiple-output (MIMO) radar can effectively obtain a large virtual array aperture. With the development of application requirements of the MIMO radar, it is necessary to further improve the angular resolution under the certain number of antennas and the certain physical aperture. Further, the MIMO array should be designed according to practical applications. Hence in this paper, th...Show More
