摘要: 提出了一种实用有效的反舰导弹末制导信号的非线性校正方法。该方法可充分利用捷联惯导信息,对雷达导引头的测量信号进行有效的校正补偿, 同时又可根据系统对校正算法实时性与精度的要求, 通过合理地调整滤波算法节点数来满足系统的设计要求, 从而大大地提高反舰导弹末制导的导引精度。该方法的有效性在某型超音速反舰导弹末制导信号校正仿真中得到验证。

Abstract: In this paper, a practical and efficient approach is given to the nonlinear correction of terminal guidancesignal( NCTGS) fo r an ant iship missile. T his approach makes correction to radar-seeker signal efficiently by makingt he best use of SINS information, and meets real time and precision demanded by system by adjusting nodal pointnumber of filter, and incr eases the precision of terminal guidance. Simulation results for terminal guidance signal correction of supersonic antiship missiles have prov ed the validity of the approach.

Key words: antiship missile, terminal guidance, signal correction, nonlinear Gauss-Hermite filtering
