摘要：

With the development of economy and military technology, exploitation of marine resources and construction of underwater projects are widely concerned, which make identification technology of underwater targets become a popular issue. Based on laser interferometry, this paper proposed a method of extracting frequencies for dual underwater acoustic signals. An experimental platform was set up in the optical darkroom, a series of experiments were made subsequently. Experiments show that the repeatability of extraction of frequency of dual underwater acoustic signals was less than 1Hz.
