Abstract

Today the use of acoustic countermeasure equipment has become the main means in submarine defense torpedo operation. Combination of acoustic countermeasure equipments are used during the operation so that we can amplify the countermeasure effect. Based on the subject of the acoustic countermeasure equipments’ combined use, this paper analyses the interference between these soft kill countermeasure equipments including gas curtain, acoustic decoy and acoustic interferometer, summarizes the advantages and disadvantages of the different combined use of acoustic countermeasure equipments.

Highlights

  • Underwater acoustic countermeasure is one of the key technologies of anti-torpedo

  • Combined use can observably increases the effect, but the effect of anti-torpedo can be decreased by wrong combination of underwater acoustic countermeasure equipment

  • Correct combination of underwater acoustic countermeasure equipment is very important in anti-torpedo warfare

Summary

Introduction

Underwater acoustic countermeasure is one of the key technologies of anti-torpedo. There are two kinds of underwater acoustic countermeasure equipment at present, soft kill countermeasure equipment and hard kill countermeasure equipment. The soft kill countermeasure equipment mainly includes acoustic self-guided decoy, acoustic interferometer, gas curtain and so on. The effect of anti-torpedo is very limited if using underwater acoustic countermeasure equipment separately. Combined use can observably increases the effect, but the effect of anti-torpedo can be decreased by wrong combination of underwater acoustic countermeasure equipment. Correct combination of underwater acoustic countermeasure equipment is very important in anti-torpedo warfare. This article analyses mutual interference when multiple kinds of soft kill countermeasure equipment are used in combination, and summarizes the advantages and disadvantages of different combinations
