摘要：The world is experiencing a rapid rate of urban expansion mainly caused by the rapid population growth. Remote sensing images can give patterns of urban growth, but urban areas are difficult to map because of the wide range of spectral signatures, sometimes combined with the occurrence of mixed pixels. So, some effective new remote sensing means should be developed. Inspired by recent advance in multiple-input and multiple-output (MIMO) radar, this paper investigated the applications of MIMO SAR (synthetic aperture radar) for urban mapping. The fundamental difference between MIMO SAR and other SAR is that the latter seeks to maximize coherent processing gain, while MIMO SAR capitalizes on the diversity of target scattering to improve imaging performance. This paper deals with conceptual analysis, as opposed to technological implementation. The system concept, signal models, and corresponding processing algorithm are formed. Some potential applications are investigated. It is shown that MIMO SAR may provide a satisfied solution to urban remote sensing
