巡飞侦察弹药定位精度及误差校正方法

Location Precision Analysis and Error Correction of Loitering Reconnaissance Munitions

巡飞侦察弹药在进行战场侦察和目标定位过程中,由于惯性导航设备测量误差的存在,使得侦察设备获取的目标位置信息误差较大。文中从误差产生的原因入手,对巡飞侦察弹药的定位精度进行分析,并提出了一种通过引入标定点位置信息对惯性导航设备的测量误差进行校正的方法,仿真结果表明:该方法能够有效的对导航设备的测量误差进行校正,极大的提高了目标定位精度。

When loitering reconnaissance munitions is conducting battlefield surveillance and target location, measurement errors of inertial navigation system make the target position obtained by reconnaissance equipments be fault. In this article, the reasons for the errors were given, and location errors of reconnaissance loitering munitions were analyzed, an error revising method was also proposed to revise the large measurement error made by inertial navigation system based on landmark information. Simulation results show that the algorithm can effectively correct measurement error and improve target localization accuracy.
