Analysis of Impact of the Former Running Noise on Active Acoustic Homing Detection of the Latter during Two Torpedoes Salvo and Countermeasures

Abstract

In anti-submarine warfare, the salvo of two active acoustic homing torpedoes is the main torpedo attack method for submarines, which can expand the search area of the torpedoes and cover a larger target scattering zone. Based on analyzing the methods of salvo of two active acoustic homing torpedoes, the organization and implementation of parallel salvo, and the impact mechanism of the former torpedo’s running noise on active acoustic homing detection of the latter, a model to describe the impact of the former torpedo’s running noise on the latter’s active acoustic homing acquisition range is developed. According to the results of a numerical example, the former torpedo’s running noise has a significant impact on the active acoustic homing acquisition range of the latter torpedo; the impact differs from the interval between the salvo of the torpedoes. Finally, suggestions are provided on how to reduce the impact of the former torpedo’s running noise in actual operation.
