建立了导弹防御系统仿真模型,对跳跃式弹道导弹的突防效能进行了分析。
Aimed to retard the response of a ballistic missile defence system, wavy trajectory with three crests was designed in this article to replace the traditional parabola trajectory.
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,从而大大地提高了弹道导弹的突防能力。
A new redundant Booth algorithm for radix8 and a novel leapfrog Wallace tree structure are presented for enhancing comprehensive performance of multiplier.
