Abstract: |
Considering the integrated inertial navigation system(INS)/synthetic aperture radar(SAR) navigation system used in the mid-last-flight of boost-glide missile,this paper establishes an error transfer model and observing model of INS in the launched inertial coordinate system,presents a transfer alignment method of the onboard master INS and SAR antenna-additional IMU.Mathmatic simulation validates the effectiveness of the method. |
Key words: transfer alignment SAR Antenna-Additional IMU |
