摘　　要：潜艇使用鱼雷对位置散布目标实施攻击时,总期望鱼雷能够通过机动搜索覆盖目标位置散布区域,提高发现概率。扩展螺旋弹道环绕的中心点是固定的,对机动目标的搜索效果不理想。扩展偏螺旋机动搜索弹道克服了扩展螺旋弹道的缺点,使其能够围绕具有一定速度的目标散布区域实施相对弹道为扩展螺旋的机动搜索,较好地覆盖目标散布概率密度较高的区域,明显提高发现目标概率。When a Submarine attacks location dispersion targets by a torpedo,it is desired to cover target position dispersion areas by torpedo maneuver searching to increase the finding probability.The central point of expanding spiral trajectory surround is fixed,the searching effect of maneuvering targets is not ideal.The expanding partial spiral maneuering trajectory overcame the defects of expanding spiral trajectory,making the spiral trajectory move around target dispersion position areas,at a certain speed to implement the relative trajectory to expand the maneuvering search of expanded spiral and to cover target position area where target dispersion probability density is high better,the target finding probability can be improved significantly.
