    Abstract
  • Traditional method for estimating torpedo hit position by observation of torpedo trail brings big error. In this paper, the mathematical principle of the traditional method is analyzed, and mathematical models of turn angle shooting of a straight running torpedo are established through geometrical analysis. Moreover, the revising principle of the torpedo leading angle is explored by converting the encounter between torpedo and target into the encounter between torpedo fore-trail and target, and calculation models of the leading angle revision are constructed. In addition, the possible error in the revising course is analyzed. Simulation result verifies the feasibility and validity of the proposed method.
