Aimmed to retard the response of ballistic missile defence system , the wavy trajectory with three crests is designed in this thesis to replace traditional parabola one . this kind of trajectory make anti - defence system have lots of difficulties to detect and compute the track and destination of ballistic missiles before reentry . so , applying the wavy trajectory can greatly improve the anti - defence ability of ballistic missiles
从延缓导弹防御系统的早期预警时间着手，将传统弹道导弹的抛物线弹道中段设计成有多个波峰的跳跃式弹道，使得探测系统在导弹再入大气层之前，很难准确探测和计算导弹的落点，使得防御系统防不胜防，从而大大地提高了弹道导弹的突防能力。
