| Abstract: | Based on the introduction to the principle of multi azimuth beam SAR system, the origin of ambignity of multi azimuth beam SAR is analyzed. The formula to compute range ambiguity for multi azimuth beam SAR system is presented and a simulation example is given. The results of the paper can be reference for designing high resolution wide swath SAR system. |
