美国发明了一种诱饵弹头,它能模拟较大型的弹道导弹弹头从外层空间再入大气层时的特性。这种轻型诱饵弹头两端装有大比重配重,能产生高惯量和减低振荡频率,使其具有弹道导弹弹头再入大气层期间的振荡频率和减速特性。可以用各种方法探测和摧毁再入大气层时的弹道导弹弹头。这些探测方法一般是靠观察再入体的减速特性和振荡频率特性来寻找弹头的。振荡频率 The United States invented a decoy warhead that simulates the behavior of a larger ballistic missile warhead from the outer space into the atmosphere. This lightweight bait warhead is equipped with a large proportion of counterweights at both ends to generate high inertia and reduce the frequency of oscillations so that it has the oscillation frequency and deceleration characteristics of the ballistic missile warhead reentry into the atmosphere. Various methods can be used to detect and destroy ballistic missile warheads that re-enter the atmosphere. These probing methods generally look for warheads by observing the deceleration characteristics and oscillation frequency characteristics of the reentry body. Oscillation frequency
