Mathematical Account of the Node Equations for Wide Band SAR Image Reconstruction

摘要

A cumulative integration method for SAR processing is presented. A low resolutionimage available at a certain time along the synthetic aperture, together with the data registered at this moment of time, form the basis for constructing an image of successively improved resolution. The approach seems suitable for real time imaging, motion compensation, adaptive radar, and whenever continuous control over the imaging process is required. The paper discusses application of the method to the extreme situation of ultra wide band, low frequency SAR. The method is demonstrated by several numerical tests.
