Application of BDS/INS integrated navigation system in airborne SAR
Airborne synthetic aperture radar (SAR) imaging requires high speed data rate to measure the instantaneous motion information of the antenna in order to make the SAR motion compensation.High precision BeiDou Navigation Satellite System(BDS)/ inertial navigation system (INS) integrated navigation system with its high data rate,high precision measurement position,velocity,attitude and other characteristics of motion information is particularly suitable for airborne SAR motion compensation.Therefore,for the high precision BDS/INS integrated navigation system used in airborne SAR imaging is studied,using the method of computer simulation reveals that the measurement error of BDS/INS integrated navigation system in SAR image mapping and restriction relations through the analysis of the key parameters of focusing and positioning in SAR images,set up between BDS/INS integrated navigation system and airborne SAR index system is suitable for real-time airborne SAR system design of BDS/INS integrated navigation system provides the basis,with strong practical engineering value.
