一、前言目前反潜技术发展到比较高的水平,潜艇受到的威胁增加,但潜艇技术也同时获得长足的进步,尤其是噪声治理得较好的潜艇仍是各国在战争中最具威胁力的武器。潜艇之所以有这样高的地位,就在于它的隐蔽性,而影响潜艇隐蔽性的主要因素是辐射噪声。目前,探测潜艇的最有效的办法仍然是 I. Introduction At present, anti-submarine technology has developed to a relatively high level, and submarines are under threat. However, submarine technology has made great strides at the same time. In particular, submarines with better noise control are still the most threatening weapons in various countries during the war . The reason why the submarine has such a high status lies in its concealment, and the main factor that affects submarine concealment is radiated noise. Currently, the most effective way to detect submarines remains
