摘要
针对密集MIMO雷达在性能方面研究存在的不足,指出了密集MIMO虚拟孔径的本质,推导出密集MIMO雷达测角精度和孔径积累得益,仿真给出了两种雷达阵列模型的测角精度。试验结果表明,与相控阵雷达进行对比,当积累时间相同时,密集MIMO雷达综合探测性能较差,必须通过增加积累时间来提高探测性能。
Recently, the co-located multi-input multi-output （MIMO） radar has become the focus of intensive research, but the performances achieved are not satisfied. In this paper, for the co-located MIMO radar, the nature of virtual aperture is researched. The angle measurement accuracy and the gain of aperture accumulation are also derived. In order to verify the detection performance, an experimental platform has been built and the experiment to detect the airplanes has been developed. Finally, the comprehensive properties of co-located MIMO radar are studied.
