摘　　要：新一代近距格斗空空导弹具有机动能力强、制导精度高的特点,可用于舰载垂直发射进行近程反导拦截作战。建立了垂直发射的三自由度弹道仿真数学模型,针对近距格斗空空导弹用于舰空反导拦截时初始段存在的探测与制导问题,提出了一种工程上易于实现的导引策略:利用目标方向信息,在探测线上构建随导弹移动的虚拟目标运动,用虚拟目标将垂直发射的导弹按比例导引律引向来袭目标,在弹目接近过程中,导引头完成对弱小目标的稳定截获并随即转入末制导段。最后对想定条件下的反导拦截进行了仿真分析,验证了该导引策略有效性。The new generation air-to-air missile for short range dogfight has the characteristics of high maneuverability and high guidance precision, which can be used as shipborad short range antimissile missile. A 3-DOF mathematical model of the vertical-launched missile was built up. In order to solve the problem of detection and guidance when a short range dogfight air-to-air missile is used to intercept anti-ship missile, a practical guidance method was proposed. Using the target direction information, a virtual target that moved on the detection line was introduced to guide the vertical-launched missile to fly to the target by the proportion guidance law. In approaching process, the IR seeker could capture the weak and small infrared target stably and then change to the terminal guidance state in time. Finally, an intercept simulation with the 3-DOF mathematical model illustrates the effectiveness of the guidance method.
