基于“标准-3”动能拦截弹的顺轨拦截方法研究

Research on Interception along Trace Based on Standard Missile-3

摘要:

提出了针对大气层外机动目标的顺轨拦截方法,能够大幅度降低目标与拦截器之间的相对速度,缓和拦截器的过载需求,避免脱靶现象。采用“标准-3”拦截弹的公开参数建立数学模型,对大气层外机动弹头的顺轨拦截过程进行了仿真研究,仿真综合考虑了助推器和拦截器的质量变化、末制导初始对准误差、导引头的测量误差和盲区、动力学系统的响应延迟和过载约束。结果表明,在处于速度劣势的情况下,拦截器能够对机动目标进行精准碰撞,验证了顺轨拦截方法的工程实践意义。

Abstract:

Interception along trace aiming to maneuvering target is proposed in this paper, which can reduce the relative velocity between interceptor and target and requirements of interceptor acceleration to avoid missing. mathematical model of standard missile-3 is established to study the interception process,the simulation considers about mass changing of boosters and interceptors, initial alignment error of terminal guidance, measuring error and blind area of seeker, response delay of dynamic system and acceleration limit. The results shows that interceptor can hit maneuvering target accurately while target is faster than itself, which indicates the practical significance of interception along trace.
