| Abstract: | As a high resolution imaging radar, SAR applies in many fields. In combined navigation system, of vehicle, image matching by using SAR image could greatly improve the precision of the navigation system. This paper mainly introduces the current situation and development of SAR, especially the application of SAR in combined navigation system of vehicle. Finally the principle, structure and simulation results of INS/GNSS/SAR combined navigation system which has high precision, fault tolerance and autonomy are presented. |
