多点源作用下反辐射导弹导引信号的形成

目前抗反辐射导弹攻击已有多种途径,如反辐射导弹来袭告警、采用低截获概率雷达、对反辐射导弹进行有源诱偏、对来袭反辐射导弹进行硬摧毁以及诱偏和硬摧毁相结合技术等.其中,利用有源诱偏抗反辐射导弹是一条行之有效的途径.文中推导了多点源作用下合成电磁场模型,在地面雷达站球面坐标系下建立了合成场等相面梯度矢量方程;利用直角坐标系与球面坐标系的转换关系及弹体坐标系与地面雷达系的转换关系,建立了反辐射导弹导引信号的模型;通过选取不同的β(诱偏源辐射功率与雷达站辐射功率的比值)值及考虑ARM导弹从不同的方向来袭情况对多点源合成场诱偏抗反辐射导弹过程进行了仿真.文中所建立的反辐射导弹导引信号模型对于通过仿真来全面和深入分析诱偏抗反辐射导弹的效果作了基础性准备.

Formation of guidance signal of anti-radiation missile under the action of multiple sources

An anti-radiation missile(ARM) is a powerful weapon for detecting and damaging or destroying an enemy's radar and electronic facilities.Various methods have been proposed and used to counter an ARM,including warning of the ARM's attack,adopting low probability intercept radar,destroying the ARM with a luring missile,and perhaps the most efficient method,decoying the ARM with baiting sources,which has been used on the United States' "Patriot" missile.Here, a guidance signal model for an ARM has been deduced that uses a synthesized electromagnetic field under the action of multiple sources.Under the spherical coordinate system of a ground radar station,equiphase surface gradient vector equations were established.Based on the relation of a rectangular coordinate system and spherical coordinate system,and the relation of the body coordinate system and ground radar coordinate system,a guidance signal model of ARM was formed.
