摘　　要：利用数学仿真计算了由重力、攻角等因素引起的跳跃式弹道的速度损失,分析了跳跃式弹道速度利用率、射程和突防能力等性能,并与抛物线弹道进行了比较.结果显示,相比于抛物线弹道,跳跃式弹道的速度利用率、射程有所降低,但其包括助推段、飞行中段、再入段在内的全程突防能力都显著提高,且在总冲量保持不变的情况下,通过合理分配推力、工作时间和攻角,可以最大限度地达到速度利用率、跳跃幅度和射程的最优效果.By mathematical simulation, the velocity loss of skip trajectory caused by gravity and attack angle was calculated. The performances of skip trajectory, such as velocity availability, firing range and penetration ability, were analyzed, and they were compared with parabolic trajectory. The results show that the velocity availability and firing range of skip trajectory are lower than those of parabolic trajectory, but the penetration ability of whole trajectory including boost phase, flying phase and reentry phase are improved remarkably. Under the conditions of invariable total impulse, the velocity availability, skip amplitude and firing range can be optimized farthest by reasonably distributing push force, action time and attack time.
