Description

The invention relates to long-distance radio communications and can be used in the organization of two-way communication and navigation without surfacing an object immersed in the aquatic environment, for example, a submarine, with underwater, surface, ground, airborne objects and spacecraft, including when covering the water surface with ice.

In modern means of long-distance and ultra-long-range radio communications with underwater (underground) objects operating in the mode of radio absorption, very low-frequency (VLF), ultra-low-frequency (VLF) and extremely low-frequency (ELF) radio waves are used in the frequency bands 3-30 kHz, 30- 300 Hz and 3-30 Hz, which correspond to wavelengths of 100 km-10 km, 10,000 km-1,000 km and 100,000 km-10,000 km. Ultra-long VLF radio waves with a wavelength of more than 10 kilometers propagate in a spherical Earth-ionosphere waveguide [1-3]. Reflecting from the ionosphere, they spread over the horizon for thousands of kilometers and are able to penetrate into the depths of the oceans to the depth of the skin layer. For example, radio waves emitted by a super-transmitter with a power of up to 2 megawatts in the operating frequency range of 15-60 kHz (wavelengths of 5 km-20 km) penetrate into sea water to a depth of 10 meters. The data transfer rate in this case is up to 300 bps. The huge dimensions of the antennas are the main brake on the way of creating and using VLF radio stations and VLF radio waves. In addition, for two-way VLF radio communication, the removal of antennas into the atmosphere is required (patents RU No. 2108675, No. 2103824).

Hertz VLF and ELF radio waves are generated by an electric discharge with a power of several tens of megawatts (the current through the antenna reaches 300 A), which is driven through two giant "electrodes" constructed in the ground. With such large generation powers, the power of the emitted radio wave is only 0.5-1 W [1]. The antenna in this case is planet Earth itself. Hertz radio waves propagate in the Earth-ionosphere waveguide channel for tens of thousands of kilometers, so they can be received anywhere on the surface of the planet. The length of such radio waves is comparable with the radius of the Earth, therefore, the transmitting and receiving antennas in this case should have gigantic dimensions. For the transmission of VLF and ELF radio waves, antenna fields on land of hundreds of square kilometers are used. Huge immersed and long cable towed antenna devices or magnetic loop antennas that receive signals under water are smaller, but they are not able to transmit hertz radio waves from under water [4]. At a frequency of about 100 Hz, the transmission speed in one session is three characters every 5-15 minutes. Signals come directly from the earth's crust or from the surface skin layer of the ocean.

The penetration depth of electromagnetic energy into water (or another medium) can be calculated by the formula:

where f is the frequency of the electromagnetic wave from 3 Hz to 300 Hz;

μ is the magnetic constant, μ = 4π⋅10 ^-7 GN / m; π = 3.14;

σ is the electrical conductivity of sea water from 1 to 4 Siemens per meter (S / m).

Using the lowest frequencies from 3 Hz to 300 Hz (ELF and ELF), it is possible to obtain a depth of underwater radio reception of more than 100 m. Therefore, for communication with remote deep-submerged underwater objects (submarines, underwater vehicles, bathyscaphes, underwater houses, etc.) a communication system of the ELF / ELF range is proposed. Electromagnetic waves of this range are suitable for solving this problem due to their ability to penetrate into the thickness of sea water to a considerable depth and spread over thousands of kilometers. In addition, in comparison with electromagnetic waves of other ranges, the propagation of ELF / ELF signals in the ground-ionosphere waveguide is highly stable even when various disturbances arise in the ionosphere [1, 2]. It should be noted that the gigantic dimensions of the transmitting antennas, which cannot be installed on a submarine, do not allow transmitting ELF / ELF signals from under water.

To receive radio signals from an underwater object on ultra-long radio waves, submerged receiving antennas are currently used, which are long cable towed antenna devices or magnetic loop antennas [4].

Known methods for long-distance radio communications with surface objects using radio channels in the ranges of short, medium, long and ultra-long radio waves and with underwater objects at ultra-low and extremely low frequencies [3, 5, 6].

The disadvantage of these methods and systems for their implementation to ensure long-distance radio communication with an underwater object is the use of a floating antenna device released to the water surface.

The known method of one-way communication with an underwater object, in which the reception of VLF radio waves (at a frequency of 14-30 kHz) and ELF radio waves (at a frequency of 76 Hz) is carried out on a towed cable antenna loop type AS-1554 BRM (20), produced for the hull of a submarine to a length of 610 m with ascent due to buoyancy [5, 6].

The disadvantages of this method are the limitation of the functionality of the communication system associated with the practical impracticability of transmitting a signal directly from an underwater object due to the technical impossibility of the antenna used to emit large powers.

There is a method of long-range one-way radio communication using ultra-low frequencies of radio waves experiencing very low attenuation (about 1 dB per thousand km at f = 100 Hz) and high signal stability during propagation in the Earth-ionosphere waveguide with relatively low attenuation during propagation in an aqueous medium [ 16]. The method provides the possibility of one-way radio communication with an underwater object in any geographical coordinates and is based, at a given operating frequency, on determining the power of the radio transmitter, which will provide communication at a depth of immersion of an underwater object in the area of certain geographical coordinates.

A known system of one-way communication [7], in which, the reception and registration of radiation generated by the ELF / ELF generators is carried out using a towed cable antenna, antenna amplifier and receiver of the ELF / ELF range, located on board the underwater object, characterized in that the transmitting special The antenna system located on the shore uses a high-voltage power line several tens of hundreds of kilometers long, and another antenna lobe, along which a reverse current flows towards the generator, ra laid deep underground within the boundaries of the skin layer at a depth of about 10 km above the ground.

A known system of one-way communication of the VLF and ELF range with deeply immersed and distant objects [8], which is a coastal radio complex of the VLF / ELF range containing "n" sinusoidal current generators (to reduce the total generation power) loaded on extended, low-lying horizontally oriented transmitting antennas with grounding conductors at the ends, the reception and registration of radiation generated by the ELF / ELF generators being carried out using a towed cable antenna, antenna antenna the driver and receiver of the ELF / ELF range on board the underwater object.

The positive effect of the system is that the system provides high reliability in the conditions of induced interference using a power line (power transmission line), which is one of the elements of the antenna hundreds of kilometers long, as well as increased power, and electromagnetic fields are recorded at remote and deep objects .

The closest in technical essence to our invention is a method for two-way communication of the ELF and ELF ranges with deep-submerged and remote objects [9], in which the towed low-frequency underwater system provides detection and communication with the underwater object by transmitting and receiving ultra-long-wavelength VLF signals during operation with a long surface antenna array towed behind a surface object.

The disadvantages of this method is the reduction in the functionality of the communication system due to restrictions on maneuvering the surface object, as well as the limited range of frequencies used and the complete absence of stealth.

The need to use bulky antennas and heavy-duty radio transmitting systems creates fundamental problems for creating two-way radio communications in the VLF, VLF, and ELF radio waves. In addition, at low frequencies it is impossible to provide communication with aircraft and spacecraft, and information transfer has low informative capacity and transmission speed (in fact, telegraph mode), a low degree of stealth and noise immunity [1-6].

The objective of the invention is to improve the method of two-way long-distance radio communication of an underwater object with underwater, surface, ground, air and space objects in the EHF / UHF ranges of radio waves.

The technical result of the invention is to simplify the design and reduce the size of the receiving-emitting antennas and receiving and transmitting devices, reducing the power of the emitted radio waves, increasing the information content and secrecy of radio communications.

The technical result achieved is achieved by the fact that in the method of two-way long-distance radio communication with an underwater object of underwater, surface, ground, airborne objects and spacecraft, including when covering the water and earth’s surfaces with ice, radio waves with extremely low density are used to receive and transmit information radio signals power of 10 μW / cm ² and lower at the natural resonant frequencies of the radio transparency of the aquatic environment in the EHF and microwave ranges.

At the same time, tunable and resonant fixed carrier oscillators of the EHF and microwave ranges and highly sensitive radios at a fixed microwave or EHF resonant frequency, transmitting and receiving contacted and remote directional low-noise antennas and antenna systems, means, are used for transmitting and receiving informational radio signals. encoding, decoding and processing of data located in places of reception and transmission of radio signals on resonant carriers often tach aquatic environment:

EHF: 50.3; 51.8 GHz and harmonics doubling: 100.6; 103.6; 150.9; 155.4 GHz and others;

EHF: 64.5; 65.5 GHz or average frequency 65 GHz and harmonics doubling: 129; 131 GHz and others;

Microwave: 0.25; 0.5; 0.985; 1 GHz and harmonics doubling 2 GHz and others.

To transmit and receive informational radio signals, use the SPE effect of converting resonant frequencies in water EHF → microwave 1 GHz: the transmission resonance EHF, the reception resonance microwave 1 GHz. They also use modern digital formats of vector modulation of the carrier frequency, for example, BPSK, QPSK, QAM or other derived forms from them, which provide spectrally more efficient communication when working with weak signals with an extremely low signal to noise ratio.

When transmitting an informational radio signal from a surface, space or other aircraft under water, the power flux on the surface of the water should not exceed the value Imax = 10 μW / cm ² .

Reception and transmission of informational radio signals in the aquatic environment is carried out in the region of the natural boundaries of the existence of the intensity of informational radio emission in water.

The claimed method of communication of the extremely high-frequency and microwave ranges with deeply immersed and distant objects is carried out using an on-board transmission system consisting of a master EHF / microwave generator; a modulator; control, protection and automation systems; power amplifier; transmitting and receiving low-noise directional antenna systems of magnetic type, consistent with the aquatic environment; indicator of radiation power of the antenna, highly sensitive receiver and demodulator. The reception and transmission of information signals is carried out by extremely low-intensity radio waves with a power density of less than 10 μW / cm ² at the natural resonant frequencies of the resonant transparency of water in the EHF / microwave (mm / dm wavelength) ranges. Transformations of transmitted signals - modulation and coding are carried out by generators, mainly vector, using crypto routers; amplification of weak signals recorded by the receiving antenna, frequency conversion, separation of information signals from the background and noise, demodulation and decoding are carried out by ultra-sensitive radios. With the transition to the regime of radio transparency of the aquatic environment, access to the use of internal "information-wave" processes occurring in the aquatic environment is opened. Transceivers using resonant frequencies of the aquatic environment will be able to provide stable two-way radio communication with underwater, surface, ground, airborne in the atmosphere and spacecraft.

Using the GLONASS global navigation satellite system will allow you to transmit a radio signal from an underwater vehicle to anywhere in the world.

With the transition to the microwave and EHF ranges, the problems of VLF and ELF radio communications in terms of power, information content, stealth, antenna dimensions are removed and a new unique opportunity is acquired for small-sized two-way remote radio communications: water-water, water-atmosphere-water and water-atmosphere-space-atmosphere- water (or land).

Used in the present invention, the effect of resonant radio transparency of water at resonant frequencies was found in the author's radiophysical studies [10-16].

The peculiarity of the aqueous medium is that the aqueous molecular structures are in the vibrational resonance-wave state, forming the internal low-intensity resonant-wave electromagnetic (EM) field of the EHF and microwave ranges.

In the resonant-wave state, the aqueous medium is “radiolucent” for low-intensity “resonant” EHF and microwave EM waves. At resonant frequencies, radio waves are emitted, received and propagated, “broadcast” in the aquatic environment. Therefore, in contrast to the known absorption resonances in optics - “absorption” resonances, these resonances are defined as “translational resonances”, or, in short, “trans resonances” (TP), and frequencies and radio waves as “trans resonances”.

The radio transparency effect occurs at an extremely low power density level P≤10 μW / cm ^{2 of} radio waves in the EHF and microwave ranges as a result of the transition of molecular water oscillators from the nonlinear vibrational absorption mode to the linear adequate resonance radio transparency mode with the change in the energy interaction of external EM waves with the aqueous medium by "Informational", which includes frequency, polarization, frequency-phase synchronization, intensity, modulation. At higher power densities, external radio waves in water are absorbed.

Thus, the “code” for the entry of radio waves into the volume interaction with the molecular system of the aqueous medium is simultaneously the upper threshold of the power density P≤10 μW / cm ² and trans-resonant frequencies. This means that the resonant "radio transparency" of aqueous media is encoded with two keys.

The basic fractal-cluster model of the molecular wave structure of water oscillators, consisting of molecular fragments — triads, hexagons, first-order clusters and a system of doublets of natural transresonance frequencies, is presented in FIG. 1 and in table 1, where j is the magnetic dipole moment, and p is the electric dipole moment; H, E - magnetic and electric field.

In doublets, the first frequencies correspond to transverse vibrations of dipole moments with respect to the field direction, and the second frequencies correspond to longitudinal vibrations. Note that in constant magnetic and electric fields, “half” frequencies of 25.1 N arise; 25.9 N GHz and 32.2 E; 32.7E GHz, which justifies the dipole nature of trans-resonant radio waves and interstructural bonds in water.

Until now, the resonance-wave state of aqueous media has been actively and successfully studied and used in medicine for the purposes of diagnosis and therapy. Therefore, the distance of the information use of resonant radio waves in the aquatic biological environment was limited by the size of objects within a meter, which was quite sufficient for medical purposes [10-16]. Special studies of two-way radio communication and its range in water at the resonant frequencies of the aquatic environment have not been conducted.

The method of two-way distant resonant EHF / microwave radio communication with an underwater object is implemented as follows.

Before starting direct experiments on radio communications, trans-resonance microwave spectra of the radio transparency of sea and fresh water were recorded in comparison. The experiments were carried out using the method of trans-resonant EHF / microwave radiospectrometry [13] according to the radio spectrometric scheme for recording the spectra of resonant radio transparency of water shown in FIG. 2, and including a tunable microwave frequency generator 1, a microwave receiver-radiometer 2, a radiating horn antenna 3, a receiving applicator antenna 4, attenuators 5, radio waves 6 and water 7 in a radiolucent capsule.

As a microwave source of electromagnetic waves, the panoramic generator Ya2R-74 was used, emitting a remote standard wideband microwave horn antenna of the electric type linear polarization P6-23A with an opening of 30 × 40 cm ² , a receiving contact double-circuit half-wave (circuit length λ / 2 = 2.5 cm) magnetic type applicator antenna matched with water [13]. At a frequency of 1 GHz, the length of the radio wave in an aqueous medium is λ = 5 cm (in air 30 cm).

The intensity of the transmitted signal I was recorded by a microwave radiometer (produced by NPO TELEMAK, Saratov) with a central frequency of microwave reception of 1 GHz in the band of 25 MHz, maximum sensitivity of 0.1 K (10 ^-17 W), integration time 1 s, scale signal measurements I: P = 5⋅10 ^-12 W / cm ² . The obtained trans-resonant microwave spectra of the radio transparency of sea and fresh water are shown in FIG. 3.

From a comparison of the spectra it follows that the base trans-resonant frequencies of sea and fresh water 985 MHz and 1000 MHz are identical. This result gives grounds for the use of resonant radio waves in remote radio communications in the areas of sea and fresh water.

A model experiment for transmitting resonant radio signals of a microwave frequency of 1 GHz of a magnetic H-series through a water channel was carried out according to the scheme shown in FIG. 4, and including a 1-1 GHz microwave generator, a 2-1 GHz microwave receiver-radiometer, a radiating applicator antenna 3, a receiving applicator antenna 4, attenuators 5, water 7 in a plastic pipe, and an interference-proof box 8.

Radio signals were transmitted in water through channels in plastic pipes with a diameter of 20 mm, lengths of 4 and 5 m. The signal power density was 1 μW / cm ² at the channel input, attenuation at the radiometer input was 10 dB. The radio signal was supplied by pulses of 1: 3 seconds duration according to the point-to-dash Morse code.

In FIG. Figure 5 shows the received coded radio signals broadcast on the fresh and sea water channel with a point-dash Morse code. The graphs show that the received pulses of the radio signals reproduce the encoded information. But in seawater there is a threefold attenuation of the signal due to losses in ionic conductivity.

The options for broadcasting radio signals in open basins of fresh water from the atmosphere and in water at a distance of 15 m and a depth of 3 m are shown in the diagrams shown in FIG. 6, where: a) UHF / microwave radiocommunication from the atmosphere, b) microwave radiocommunication in water implemented using a 1 GHz microwave generator (1), 65 GHz microwave generator (1 *), and 1 GHz microwave receiver-radiometer, (2) emitting antennas (3) microwave and (3 *) EHF, receiving microwave antennas (4), radio waves (6), water (7) in pools. The use, along with a 1 GHz microwave resonance, of an EHF of an average resonant frequency of 65 GHz is based on the SPE effect of the conversion of trans-resonant EHF radio waves into 1 GHz microwave resonant waves in water [13, 14, 16].

The effects of resonant radio transparency of water and the SPE effect of the conversion of resonant frequencies in water EHF → microwave 1 GHz can be used in underwater radio communications and radar in the modes water-water, water-atmosphere-water and water-atmosphere-space-atmosphere-water (or earth )

To assess the attenuation of radio waves under experimental conditions (the power density of the radio waves at the emitting antenna was 1 μW / cm ² with the attenuators introduced at 10 dB in reception and transmission (Fig. 4)), the intensities (I) of the transmitted radio signals at a frequency of 1 GHz were measured channels of sea water with a length of 4 m - I (4) and 5 m - I (5). The specific attenuation of the radio signal determined by their ratio I (5) / I (4) = 0.77 has a relatively small value: k = 10⋅lq (0.77) = 1.1 dB / m. Taking into account the reserve for sensitivity (10 → 0) dB and power (1 → 10) μW / cm ² , the EHF / microwave range of underwater radio communication can be increased.

Note that the upper limit of the power density is P≤10 μW / cm ² and the intrinsic resonant radio emission of water is P _int. ≤ 5⋅10 ^-12 W / cm ² (which is the background in the case of reception and transmission of informational radio waves) determine the natural boundaries of the intensity of informational radio emission in water and, accordingly, the range of underwater radio communications, as well as the choice of receiving and transmitting devices for underwater radio communications.

When transmitting a radio signal from a spacecraft or other aircraft under water, it must be taken into account that when the radio signal enters the aqueous medium (i.e., on the surface of the water), the signal intensity should not exceed the value Imax = 10 μW / cm ² . On the other hand, the background intensity measured by us [12-14] (and this is the power flux of the intrinsic resonance radiation of the molecular structure of water in the absence of external excitation) is Imin ≤ 10 ^-7 μW / cm ² . Based on this, it can be concluded that the intensity of the resonant information radio emission in water should lie in the range from 10 μW / cm ² to 10 ^-7 μW / cm ² and lower, which is determined by the nature of the water. Thus, the attenuation of the maximum possible information radio signal to the maximum background level Imin = 10 ^-7 μW / cm ² is determined by the ratio Imin / Imax ≈ 10 ^-8 . This corresponds to a attenuation of 10⋅lq (10 ^-8 ) ≈ 70 dB, or in common units of -100dBm / cm ² (dBm is decibellomillivatt). Taking into account the specific attenuation k = 1.1 dB / m, the background intensity will be comparable with the intensity of the information radio signal (at Imax = 10 μW / cm ² ) at a diving depth of 70 m. Given that the actual background intensity can be Imin << 10 ^{- 7} μW / cm ² (for example, when the water temperature decreases, the vibration amplitude of molecular oscillators and, consequently, the noise power will decrease exponentially), then the EHF / microwave range of underwater radio communication can be increased by about 1.5 times (at a frequency of 1 GHz transmitting and receiving information radio signals als possible up to 100 m).

The limitation of the range of the EHF / microwave underwater resonant radio communication is due to the phenomenon of the resonant-wave electromagnetic state and the resonant radio transparency of the molecular water system. To increase the range of EHF / microwave underwater resonant radio communications, it is advisable to use a system of repeaters.

Of particular interest is the transmission and reception of information signals using polarized radio waves. Polarized information signals will be easier to distinguish from the background. This will increase the range of underwater radio communications.

To organize stable reception of information by an underwater vehicle, it is necessary to provide a sufficient information frequency band (up to 10 MHz follows from the spectra shown in Fig. 3) and the necessary excess of the signal power over the noise power, for which it is advisable to use a low-noise directional transmit-receive antenna system and a preliminary amplifier HF, possibly cooled. If the signal is transmitted from under water, then the power density on the surface of the water will be sufficient for the radio wave to be received on board the aircraft or spacecraft, since losses in the atmosphere are negligible compared to attenuation in water (recall that the absorption of radio waves in an air column from Earth's surface to outer space is equivalent

a distance of only 8 km in the horizontal direction at sea level under normal conditions).

The use of an underwater radio communication channel in the framework of the organization of interaction between underwater and surface objects or aircraft (spacecraft) will allow for a high data exchange rate (up to 10 Mbit / s - as follows from the radio transparency spectrum of water in Fig. 3) using a directional low-noise antenna system.

The method of two-way radio communication at resonant frequencies of water can be used in the fleet for communication and navigation without surfacing the device, including when covering the water and earth surfaces with ice (i.e. in the ice position), in emergency situations for radio communication with underwater objects and underwater vehicles with surface, ground, airborne objects and spacecraft, as well as in scientific research when studying the properties of the environment and objects of animate and inanimate nature immersed in this environment, for research in geology, zoology and biolo geology, hydrology and geodesy.

Thus, the claimed combination of essential features allows you to achieve the technical result.
