Abstract
At present, MIMO radar is more and more widely used in the field of radar imaging. With its unique multi transmit and multi receive system, after appropriate processing, the radar can be equivalent to a virtual array that can transmit and receive independently at the same time, which is equivalent to increasing the radar aperture and improving the resolution of radar imaging. However, in some cases, when the radar needs to provide high azimuth resolution images under certain conditions, the imaging range and resolution provided by a single radar may not be enough. The distributed multi MIMO radar imaging system model described in this paper is composed of multiple radars with the same system. Under a certain signal processing mode, through timing control, the static distributed multi MIMO radar can realize high-resolution object images in the imaging area at the same time. Under the above conditions, using certain data processing methods, the imaging system proposed in this paper can provide a larger imaging range and higher resolution, especially angular resolution, compared with a single radar.
