Abstract: That the anti-defence technologies has become less developed compared with defence technologies be?comes today one of the most acute problems faced by ballistic missiles. So, to develop anti-defence technologies is today an important means to improve the ability of survival of ballistic missiles. Aimed to retard the response of a ballistic missile defence system, wavy trajectory with three crests was designed in this article to replace the tra?ditional parabola trajectory. Wavy trajectory of missiles can embarrass the defence system in detecting and com?puting the track and destination before reentry. So, wavy trajectory may greatly improve the ability of a anti-de?fence of ballistic missiles. In this article, based on a certain land-land ballistic missile, a new kind of ballistic mis?sile was designed with an additional rocket engine, which can be ignited twice. Finally, the trajectory profile was optimized with complex algorithm to maximize tne average amplitude of three wavy.
