反导定向战斗部目标方位无线电比相测角法研究

使用防空导弹拦截来袭战术弹道导弹(TBM)是目前各主要军事大国研究的热点.反导(Anti-TBM)已成为现代防空导弹的重要作战任务之一,其难点在于如何在防空导弹和来袭弹道导弹高速交会的条件下及时准确地提取出目标的来袭方向,并控制定向起爆战斗部适时起爆.本文运用无线电比相测角的基本原理,提出了用二维比相测定目标方位角和高低角的方法,推导出了目标方位角和高低角的测角公式.将该方法应用到反导定向战斗部中,解决了反导定向战斗部确定目标方向角信息的技术难题.

Research on Target Orientation Angle Measurement with Wireless Phase Discrimination Method in Anti -TBM Aimed Warhead

Using ground-to-air missile to head off tactics ballistic missile (TBM) is the hot point in martial field today. Anti-TBM has become an important mission of the ground-to-air missile. The difficulty of anti-TBM is how to detect the azimuth and elevation between ground-to-air missile and TBM exactly and duly in the complex encounter condition. This paper introduced an angle measurement principium based on phase discrimination. A method for measuring azimuth and elevation is brought forward, which is based on two-dimensional phase discrimination. The azimuth and elevation measurement formulas are given. Using this method the problem of measuring target directional angle in anti-TBM aimed warhead was solved.
