防空导弹初制导规律

分析了用于垂直发射防空导弹初制导的三角型和指数型两种导引控制。给出了两种控制方法的导引律,计算了典型弹道的攻角、俯仰角和交班点速度等参数。两种控制律的弹道参数计算结果表明,两者均为较理想的制导方案。与三角控制律相比,指数控制律的弹道倾角误差、最大攻角和速度损失均较小,其导弹交班精度更高。

Research of Launch Guidance in Antiaircraft Missile

The guidance laws of trigonometry function and the exponent function used in the launch guidance for vertical launch missile were analyzed in this paper.The angle of attack,pitch angle and velocity at shifted point for typical trajectory were calculated.The computation results of the two guidance laws showed that both were ideal guidance method.And with the comparison,trajectory inclination error,maximum angle of attack and velocity loss of the exponent one were all smaller than those of trigonometry one.The shift accuracy of the former was much higher.
