    Abstract
  • In terms of ranging interference of an acoustic fuze due to torpedo navigation attitude changing, based on the basic principles of three-beam acoustic fuzes and interference generation, this paper applies Euler rotation theorem to spatial transformation of the beam vector and analyzes the ranging error of each beam with torpedo navigation attitude changing. Based on the acquisition of the navigation attitude data, a method is proposed to eliminate the ranging error of the acoustic fuze caused by the variation in the torpedo navigation attitude. These data are introduced into a fuze-ranging algorithm considering interference. A simulation test shows that the proposed method can effectively suppress the interference caused by the change in the torpedo navigation attitude.
