摘要 发射分集MIMO雷达具有潜在的高分辨成像能力,但成像时存在高旁瓣问题。为分析它的成像性能,该文首先建立了发射分集MIMO雷达的成像模型。通过空间频谱的支撑区分布,阐明了分集成像的高分辨性能,并着重分析了其旁瓣特性。基于谱外推的思想,提出了一种发射分集MIMO雷达融合成像处理方法,该方法能够实现MIMO雷达高分辨成像同时具有良好的旁瓣性能。仿真实验验证了该文所提方法的有效性。 MIMO radar with transmit diversity has the potential of high-resolution imaging, but the imaglng results suffer from huge sidelobes. In order to analyze the imaging performance of MIMO radar, this paper establishes an imaging model firstly. The high-resolution ability of diversity is demonstrated from spatial spectral coverage, and the sidelobe performance of diversity image is analyzed in particular. Based on spectral extrapolation a fusion imaging method for MIMO radar with transmit diversity is proposed. This method can achieve high-resolution images with good sidelobe performance. Finally, simulations are performed in order to validate the effectiveness of the proposed method.
