According to the Range Doppler imaging of static scene, a ground moving target imaging model is achieved. Based on the model, the over-complete dictionary of targets sample images with different speeds is constructed. Then the test SAR images are blocked into sub-images and the corresponding coefficients are calculated depend on the dictionary. There is a significant difference between the coefficients of background clutter and moving objects. On the basis of the difference, whether there is a moving target can be judged, simulation results have proved the validity of the proposed method.Read More
