Researching interception of near-space hypersonic cruise missile

Near-space hypersonic cruise missile has gradually entered the weaponization process, which presents a challenge to existing space defense system. Firstly, we analyze a typical trajectory of hypersonic cruise missile; we point out that its cruise segment is the phase most vulnerable to being intercepted and propose that the air-launched interceptor is a major means for performing interception. Secondly, in order to study the influence of the guidance law and the overall relevant parameters on the intercept capability of interceptor, we build a mathematical model based on interception. And by a large-scale system flight path simulation of the interceptor flying against target, we obtain the three-dimensional attack area of interceptor under different conditions. The simulation results and their analysis show preliminarily that, in order to intercept the target effectively, the dimensional attack zone should be located near the target right head airspace. Under current simulation conditions, classic proportional guidance law can not complete the task of intercepting maneuvering target. The interception range and the relevant conclusions of this paper have a certain significance for interceptor missile.
