Research on High Resolution SAR Based on Frequency-stepped Chirps

摘要：

Since the birth of the synthetic aperture radar,how to enhance the resolution is the very important direction of the SAR research,with the resolution of airborne SAR come to 0.1m,for the design of the SAR system,the realization of the ultra band signal is a difficult problem,in order to alleviate the press of the A/D acquisition and data store,adopting the technique of the bandwidth synthesis to get the range high resolution,in azimuth applying wavenumber domain method,through the azimuth processing in twodimension,solving the problem of coupling,attaining the high-resolution of the azimuth. The paper introduced the principle of a high resolution SAR system,the arithmetic of high resolution range imaging,give the simulation result,preliminary flight results and expect the future work.
