基于航迹优化的反辐射导弹飞行方案研究

Research on Anti-Radiation Missile Flight Scheme Based on Track Optimization

反辐射导弹的航迹优化问题是设计最优方案弹道或最优导引规律的问题,本文推导了航向、弹道偏角和定位误差的克拉美罗下限CRLB的关系,通过数值分析获得了仅从定位精度出发的最优航向和弹道偏角。然后针对反辐射导弹的实际应用背景,提出了适合反辐射导弹应用的优化飞行方案,通过数值分析对比了三种飞行方案优劣。

The problem of track optimization for anti-radiation missiles is the problem of trajeetory or optimal guidance for optima! design. In this paper, the relationship between the heading, the trajectory deflection and the permissible error of the CRLB is deduced by numerical analysis. Only from the positioning accuracy of the optimal heading and trajectory deflection. Then, aiming at the practical application background of anti - radiation missile, an optimized flight scheme suitable for anti - radiation missile application is proposed. The advantages and disadvantages of the three flight schemes are compared by numerical analysis.
