Abstract

Abstract

In response to the problem of solving the favorable lead angle in the case of uncertain homing range of torpedoes, the influence of homing range on torpedo firing is first analyzed. It is pointed out that when the actual homing range of torpedoes is less than its binding value, the favorable lead angle obtained from the calculation will be smaller, and the probability of torpedo discovery will be significantly reduced. Secondly, the weighted average discovery probability of torpedoes was defined, and based on this, a favorable lead angle calculation method was proposed to maximize the weighted average discovery probability. Then, based on the principle of maximum entropy, two maximum entropy distribution models for the actual homing range of torpedoes were given, and the formula for solving the favorable lead angle under this distribution model was obtained. Finally, the favorable advance angle of torpedo homing was obtained through simulation under the condition of uncertain operating distance.
- acoustic homing torpedo,
- self-guided action distance,
- favorable lead angle,
- maximum entropy distribution
