| Abstract: | Based on the difference between the forward-looking mode and the side-looking mode of airborne SAR system,the Doppler properties and azimuth ambiguity of the forward-looking SAR(FSAR) mode are analyzed.According to the FSAR property,the point target image is simulated by BS and RD algorithm.The simulation proves the analysis is right. |

| Keywords: | forward-looking mode SAR Doppler frequency azimuth resolution |
