反舰导弹对目标选择的一种新方法

超视距反舰导弹(ASM)在搜索阶段选择预定目标时,目前采用的瞄准点选择方法受自控终点的散布误差和目标机动影响较大。为此提出一种利用舰艇编队相互位置关系(MPR)选择预定目标的方法。编队相互位置关系即其余目标相对参考目标的位置,对于一个编队,选择不同的参考目标得到不同的编队相互位置关系。对发射前装订的编队,以预定目标为参考目标获得其编队相互位置关系,在末制导雷达探测到的编队目标中,若以某目标为参考目标时的编队相互位置关系与之最相似,则该目标即为所要选择的预定目标。该方法不受自控终点散布误差和编队目标整体机动的影响。仿真实验表明该方法正确选择预定目标的概率高于瞄准点选择方法。

A New Method to Target Selection for Anti-ship Missile

n search phase of over-the-horizon anti-ship missile (ASM) guidance, the scheme using the aiming point is widely used at present to acquire the correct target ship. However, it is greatly influenced by the terminal dispersion of previous self-control phase and the maneuvering of the target ship. In view of this, this article proposes a target selection method using the “mutual position relationship (MPR)”, i.e., the relative positions of other ships to the reference ship. For a ship formation, different reference ships get different MPRs. In the ship formation imported before launch, the target ship is selected as the reference ship and its MPR is computed. Then the target ship in the ship formation detected by terminal guidance radar is the one whose MPR is most similar to that mentioned above. This kind of target selection method is not influenced by the terminal dispersion of self-control phase and the consistent maneuvering of the ship formation. Simulation results show that the probabilities to select the target ships are higher than those using the aiming point scheme.
