Under the condition of strong interference, sonar equipment faces the problem of ultra-wideband joint perception processing. The solution depends on the collection of multiple sonar equipment, which has the defects of high cost, low integration and low processing efficiency. This paper introduces the basic concept of binaural positioning and separation, and analyzes the research status of binaural positioning and separation for underwater scenes by referring to the mechanism of human binaural high gain and high resolution under the condition of small aperture dual elements. Based on the combination of sonar signal processing technology, it is proposed to carry out technical approaches such as underwater acoustic signal separation technology based on prior information and binaural differentiation, and homologous auditory clue fusion technology, which can be used for the development of binaural positioning and separation technology in underwater scenes.
As the most important means of underwater information perception for submarines, the sonar system is an important guarantee for submarines to complete combat missions. In view of the demand for the development of integrated sonar, this paper starts from the modular open architecture and COTS technology, active and passive, multi-band, multifunctional integrated acoustic array, multi-array fusion processing technology, sonar performance evaluation and auxiliary decision-making , intelligent sonar and other aspects to conduct research on the current development status of integrated acoustic array technology , and analyze the development trend and technology gap.
