弹载主INS与SAR天线IMU传递对准方法

A transfer alignment method of onboard master INS and SAR antenna-additional IMU

本文以助推—滑翔导弹为研究对象,针对其飞行中、末段采用的INS/SAR组合制导体制,建立了发射点惯性系下惯导系统误差传播模型、观测模型,给出了弹载主INS和SAR天线附加IMU的传递对准方法,并通过数学仿真验证了方法的有效性.

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.
