Holographic Method for Localization of a Moving Underwater Sound Source in the Presence of Intense Internal Waves
Within the framework of a numerical experiment, the holographic processing of noise emission from a moving underwater sound source in the presence of intense internal waves, which cause horizontal refraction of sound field waves, is considered. The interference of the undisturbed and disturbed fields forms a moiré interference pattern (interferogram) that masks the interferogram of a noise source. Registration of a moiré interferogram using a two-dimensional Fourier transform makes it possible to separate the spectral densities of the unperturbed and perturbed fields. This makes it possible to reconstruct the interferogram of the unperturbed field in the presence of intense internal waves. The relative error of its reconstruction is estimated. The errors in reconstructing the range and radial velocity of the source due to horizontal refraction are analyzed.
期刊介绍：
Journal “Radioelectronics. Nanosystems. Information Technologies” (abbr RENSIT) publishes original articles, reviews and brief reports, not previously published, on topical problems in radioelectronics (including biomedical) and fundamentals of information, nano- and biotechnologies and adjacent areas of physics and mathematics. The authors of the journal are academicians, corresponding members and foreign members of the Russian Academy of Natural Sciences (RANS) and their colleagues, as well as other russian and foreign authors on the proposal of the members of RANS, which can be obtained by the author before sending articles to the editor or after its arrival on the recommendation of a member of the editorial board or another member of the RANS, who gave the opinion on the article at the request of the editior. The editors will accept articles in both Russian and English languages. Articles are internally peer reviewed (double-blind peer review) by members of the Editorial Board. Some articles undergo external review, if necessary. Designed for researchers, graduate students, physics students of senior courses and teachers. It turns out 2 times a year (that includes 2 rooms)
