What is the use of the voiceprint of the submarine, please ask how much significance is it to keep t

The voiceprint of the submarine is unique, which is equivalent to the ID card of a submarine. If the voiceprint characteristics of different submarines of various countries are collected through various means and channels, a submarine voiceprint information database can be established, and the noise characteristics of the opponent's submarine received by sonar can be compared with the records in the submarine voiceprint suspension database, and we can know which country, which model, and which submarine the other submarine is.

Submarines are distinguished by combat mission: there are strategic missile submarines and attack submarines.

Power differentiation: nuclear-powered submarines and conventionally powered submarines.

According to the underwater displacement: there are large submarines (more than 2000 tons), medium submarines (600 2000 tons), small submarines (100 600 tons) and pocket submarines (up to 100 tons).

Hull structure form is differentiated: there are double-hull submarines and single-hull submarines.

Strategic missile submarines.

It is used to carry out strategic nuclear strikes on important targets on land. Most of them are nuclear-powered, but there are also conventionally powered. The main ** are submarine-to-surface missiles and are armed with torpedoes.

The nuclear-powered strategic missile submarine has an underwater displacement of about 5,000 30,000 tons, an underwater speed of 20 30 knots, a diving depth of 300 500 meters, and a self-sufficiency of 60 90 days and nights. The conventionally powered strategic missile submarine has an underwater displacement of about 3500 tons, an underwater speed of 14 15 knots, a diving depth of about 300 meters, and a self-sufficiency of 30 60 days and nights.

Attack submarines. For attacking surface ships and submarines. There are two types: nuclear power and conventional power.

The main ** are torpedoes, mines and anti-ship and anti-submarine missiles. Nuclear-powered attack submarines have an underwater displacement of 3,000,7,000 tons, an underwater speed of 30,42 knots, a depth of 300,500 meters, some of which can reach more than 700 meters, and a self-sufficiency of 60,90 days and nights. Conventional power attack submarines have an underwater displacement of 600 3000 tons, an underwater speed of 15 20 knots, a diving depth of 200 400 meters, and a self-sufficiency of 30 60 days and nights.

The voiceprint of the submarine is like a human fingerprint, it is unique, if the voiceprint characteristics of different submarines of various countries are collected through various means and channels, the submarine voiceprint information database can be established, whether in peacetime or wartime, the noise characteristics of the opponent's submarine received by the sonar can be compared with the records in the submarine voiceprint suspension library, and you can know which country's submarine the opponent's submarine is, which submarine of which model, therefore, you can use this to decide whether to attack it.

The voiceprint of submarines is of great value for anti-submarine warfare.

The so-called submarine voiceprint is actually the noise signature of the submarine, and the most important means of detecting the submarine is to detect the noise of the submarine through sonar.

It has been said that it is quite difficult to search for the sound of a submarine because of the large background noise on the seabed. In the past, mute technology was not developed, and the continuous noise of the normal operation of submarines (the sound of engine and thruster operation) was relatively easy to hear directly with passive sonar. In the future, with the popularization of shock-absorbing floating rafts, sound-absorbing tiles, and large roll propellers, this kind of continuous noise has been greatly reduced, and it is much more difficult to fish out of marine background noise. At this time, it is natural to need the voiceprint of a specific submarine as the basis for comparison and filtering, otherwise it is extremely difficult to hear a silent submarine in the vast sea without knowing anything.

The voiceprint is used to catch submarines in a complex marine environment and is a reference for catching submarines. The voiceprint of submarines is of great value for anti-submarine warfare.

Voiceprint is the spectrum of sound waves that carry speech information displayed by an electroacoustic instrument. Modern scientific research has shown that voiceprints are not only specific, but also relatively stable. In adulthood, the human voice can remain relatively stable for a long time.

Experiments have shown that whether the speaker deliberately imitates the voice and tone of another person, or whispers softly, even if the imitation is vivid, the voiceprint is always different. Based on these two characteristics of the voiceprint, the investigators can test and compare the voiceprint of the criminal and the suspect through the voiceprint identification technology, quickly identify the criminal, and provide reliable evidence for the investigation and solving the case.

At present, many countries have regarded voiceprint identification as an important means of identifying criminal suspects, providing new clues and evidence for investigations.

1) When the voice recording materials of the offender are obtained, such as intimidation or blackmail carried out in **, or the voice of the offender is recorded in other crimes, then the voice samples of the suspect can be collected for voiceprint identification, and the appraisal conclusion can be provided for the identification or denial of the offender;

2) In the investigation or trial of a case (including civil cases), the falsity of the recorded evidence materials can be examined through voiceprint identification;

3) Through voiceprint analysis, the gender, age, and dialect (living area) characteristics of the speaker are determined, so as to provide direction and scope for the investigation work.

How much is the significance of the submarine voiceprint characteristics secret, and the significance of the hail is too great (once the voiceprint of the submarine sedan sail is leaked, the submarine will be useless).
