一种新的鱼雷垂直命中目标的制导方法

该文针对鱼雷采用前视角声纳和旁视声纳识别和跟踪目标，引入了初始导引段跟踪虚拟目标的概念，提出一种新的精确制导方法，给出了导引跟踪和垂直命中弹道的数学模型。经仿真和分析表明：该制导方法对攻击目标的初始态势几乎没有限制，即使目标为逃避攻击进行转向机动，也能垂直命中目标。

A New Guiding and Controlling Method for Perpendicular Target Impact of the Underwater Autonomous Vehicle

In view of underwater autonomous vehicle equipped with the head sonar and side sonar identifying and tracking the underwater target,a conception to track an imaginary target at initial guiding section is introduced,and a new accurate guiding method and mathematical model are presented.The ballistic of the guiding,tracking and perpendicular impact is analyzed and simulated.The results show that the underwater autonomous vehicle can almost attack a target using the guiding method of perpendicular impact at any initial state.Even if the target turns round for escaping during the attack,the perpendicular impact can also be ensured.
