MIMO-SAR Imaging and Waveform Design

This paper develops a new framework for jointly addressing the waveform design and imaging problems in multiple-input-multiple-output synthetic-aperture radar systems could be continuously transmitting wideband electromagnetic energy. Here the transmitters and receivers move along arbitrary trajectories, and the scene is assumed to be stationary.The paper begins with with the derivation of the forward model and uses this model to develop a matched-filter imaging method. Analysis of the resulting image shows that the point- spread function involves a certain wideband cross-ambiguity function, which forms the basis for addressing the waveform design problem.
