A device for determining the location of the signal source installed on a single-point observation point with one registration point of the lower frequencies of electromagnetic radiation (EMP), the level of radiation background and temperature, and with two points of registration of electromagnetic radiation (EMP), infrasound, light and seismic vibrations works as follows. If, for example, a lightning strike occurs, a gas explosion, an industrial explosion, a meteorite fall, or an ejection from a nuclear power plant (NPP) are detected, it is first possible to register fast signals at the observation point — EMR, light, and increase the background radiation level. According to any of these signals, time difference counters between fast and accompanying slow signals - infrasound and seismic signals are started, and to record emissions from nuclear power plants, a time difference counter is also started between an increase in the background radiation level and an increase in temperature. Possible fast signals of electromagnetic radiation, light determine the direction to the signal source and approximate location, and slow signals specify the location of the signal source. In the case of emissions from nuclear power plants, the approximate direction to the signal source is determined by the position of the temperature sensors that recorded the minimum difference between the time the background radiation increases and the temperature increases. From the known distance between the temperature sensors and the difference in the time of arrival of the signals to the temperature sensors, the propagation speed of the thermal disturbance is determined, according to which, taking into account the minimum difference between the time the background radiation increases and the temperature increases, the approximate distance to the signal source is determined. Reception and processing of signals are as follows. When EMR appears, the currents induced in the first block of magnetic antennas 2 from the signal source, through the fifth block of amplifiers 29, the second block of filters 30 and the fourth block of the ADC 63, enter the PC 1. Similarly, the signals of the block of light sensors 23 through the third block of amplifiers 24, the first block of filters 25 and the third block of the ADC 62 enter the PC 1, where the information processing cycle begins when the signals of the first block of magnetic antennas 2 or the block of light sensors 23 exceed the specified threshold values. The received signals of two orthogonal pairs of antennas from the first two blocks of magnetic antennas 2 installed at the registration points in the horizontal plane so that one of the two antennas of the first registration point is oriented by the maximum radiation pattern to the maximum antenna radiation pattern of the second registration point, are used to determine by known methods [ 3] angles α, β of the arrival of the EMP signal at the registration points, ie angles between the direction from one registration point to another registration point and the direction from each registration point to the EMP signal source, for example, according to the formulas

where A ₁ , A ₂ are the amplitudes of the signals of the middle frequency coming to PC 1 from the fourth ADC block 63 from the antennas of the first registration point located in the horizontal plane, and A ₁ is the amplitude of the signals from the antenna oriented by the maximum radiation pattern to the second registration point,

A ₃ , A ₄ are the amplitudes of the medium-frequency signals arriving at the PC 1 from the fourth ADC block 63 from the antennas of the second registration point located in the horizontal plane, and A ₃ is the amplitude of the signals from the antenna oriented by the maximum radiation pattern to the first registration point.

To register light within the hemisphere, a set of light sensors is used with the dependence of the signal amplitude on the coordinates, as, for example, in the US patent [4]. In the specific case, this dependence is achieved by installing optical filters on the light sensors that provide a sensitivity diagram in the horizontal plane in the form of a circle tangent to the plane of the light sensor. A pair of such light sensors directed in opposite directions provides a figure eight sensitivity diagram in the horizontal plane, like a magnetic antenna. The received signals of two orthogonal pairs of light sensors installed at the registration points in the horizontal plane so that one of the two pairs of light sensors of the first registration point is oriented by the maximum sensitivity diagram to the maximum sensitivity diagram of a pair of light sensors of the second registration point, are used to determine in a known manner [3 ] angles α, β of light arrival at the registration points, ie angles between the direction from one registration point to another registration point and the direction from each registration point to a light source, for example, by the formulas

where A ₅ , A ₆ are the amplitudes of the signals entering the PC 1 from the third ADC block 62 from the light sensors of the first registration point located in the horizontal plane, where A ₆ is the amplitude of the signals from the light sensors oriented by the maximum sensitivity diagram to the second registration point;

A ₇ , A ₈ are the amplitudes of the signals entering the PC 1 from the third ADC block 62 from the light sensors of the second registration point located in the horizontal plane, and A ₈ is the amplitude of the signals from the light sensors oriented by the maximum sensitivity diagram to the first registration point.

At the same time, the signals of the first block of magnetic antennas 2 through the fifth block of amplifiers 29 from the outputs of the second block of filters 30 pass through the sixth block of amplifiers 31 to the fourth threshold block 32. When the signals exceed the values specified by PC 1, the logical units are generated at the outputs of the fourth threshold block 32 to the third block of circuits OR 33, the output signal of which is supplied to the first block of circuits OR 10.

The received signals of the orthogonal pairs of light sensors from the outputs of the first filter block 25 are fed through the fourth block of amplifiers 26 to the third threshold block 27. When the signals exceed the values specified by the PC 1, logical units are generated at the outputs of the third threshold block 27 and fed to the second block of OR circuits 28 whose output signal is supplied to the first block of OR circuits 10.

A signal about an increase in the radiation background in the case of emissions from nuclear power plants from the output of the radiation receiver 14 through the second amplifier 15 is fed to the first threshold element 16, the output of which, when the set signal level is exceeded, a logical unit is formed that arrives at the first block of OR circuits 10.

The output signal of the first block of OR circuits 10 starts the first and second timers 11, 45, and starts the third timer 57 through the OR circuit 67. The outputs of the first timer 11 allow the passage of pulses from the first clock generator 21 through the first circuit And 12 to the block of counters 13 and prepare block of circuits And 20. Thus, the countdown begins with the moment of increasing the background radiation at the observation point.

The output signals of the second and third timers 45, 57 allow the passage of pulses from the second clock generator 66 through the third circuit AND 46 to the counter 47 and prepare the second circuit And 44, as well as through the fourth circuit And 58 to the second block of counters 59 and prepare the second block of circuits And 56. Thus, the countdown starts from the moment of arrival at the observation point of electromagnetic radiation (EMP) and (or) a flash of light of a registered phenomenon, for example, a lightning discharge.

The infrasound wave accompanying this phenomenon arrives later at the first and second infrasound recording points located at the observation point and received by the blocks of microbarometers 50 of the first and second channels, the output signals of which are transmitted to the PC 1 through the seventh amplifier block 51, the third filter block 52 and the second ADC block 61. In addition, the output signals of the block of microbarometers 50 pass through the eighth block of amplifiers 53 and the fourth block of filters 54 to the fifth threshold block 55. When the signal exceeds the value specified by the PC 1, at the outputs of the fifth threshold block 55, logical units are generated that arrive at the second block of circuits AND 56, the output signals of which, if there is an enable signal at the second inputs from the fifth timer 65, stop the counters of the second block of counters 59 and fix the time intervals between the arrivals of EMI and infrasound at the first and second points of registration. In the absence of an infrasound signal, the second block of counters 59 is stopped and reset after the end of the signal of the third timer 57.

The obtained values of the time intervals from the outputs of the second blocks of counters 59 go to a personal computer 1, where the distances A, B from the registration points to the signal source are determined by the value of the infrasound speed previously measured during calibration of microbarometers, and taking into account the obtained directions α, β to the signal source from points registration determines the approximate location of the signal source. However, the actual speed of infrasound on the track depends on the terrain and may differ from the speed of infrasound obtained during the calibration of microbarometers. To clarify the location of the signal source, the specified infrasound speed on the paths from the signal source to the registration points is determined by the known distance C between the registration points, angles α, β of the arrival of the EMP signal (light) at the registration points and time intervals Δt ₁ , Δt ₂ between the arrival of EMR ( light) and infrasound at registration points. From the resulting triangle it follows:

where A is the distance from the first registration point to the signal source,

B is the distance from the second registration point to the signal source,

C is the distance between the first and second registration points,

α, β - angles of arrival of EMR (light) at the first and second points of registration,

Δt ₁ is the time interval between the arrival of EMR (light) and infrasound at the first registration point,

Δt ₂ is the time interval between the arrival of EMR (light) and infrasound at the second registration point,

V ₁ - refined speed of infrasound along the tracks from the signal source to the registration points.

The updated speed of infrasound and the time intervals between the arrival of EMR (light) and infrasound at the registration points determine the adjusted values of A, B and the specified location of the signal source.

The seismic wave accompanying this phenomenon arrives later at the first and second points of registration of seismic waves at the observation point and is received by the seismometers 40 of the first and second channels, the output signals of which are fed to PC 1 through the first amplifier 3, the first filter 4, and the ADC 60. In addition, the output signals of the seismometers 40 pass through the third amplifier 41 and the second filter 42 to the second threshold element 43. When the signal exceeds the value specified by the PC 1, the output of the second threshold element 43 is formed a logic unit, input to the second AND circuit 44, whose output signal in the presence of an enable signal at the second input of the fourth timer 64 stops the counter 47 and detects time intervals between the arrival AMY (high beam) and the seismic waves at the first and second point registration. In the absence of a seismic signal, the counter 47 is stopped and zeroed after the end of the signal of the second timer 45.

The obtained values of the time intervals from the outputs of the counters 47 go to a personal computer 1, where the distances A, B from the registration points to the signal source are determined from the known value of the speed of seismic waves for a given region, and taking into account the received directions α, β to the signal source from the registration points, it is determined approximate location of the signal source. However, the actual speed of seismic waves on the track depends on the terrain and may differ from the known regional speed of seismic waves. To clarify the location of the signal source, the specified speed of seismic waves along the paths from the signal source to the registration points is determined by the known distance C between the registration points, angles α, β of the arrival of the EMP signal (light) at the registration points and time intervals Δt ₃ , Δt ₄ between the arrival of the EMP (light) and seismic waves at the registration point. From the resulting triangle it follows:

Δt ₃ is the time interval between the arrival of EMP (light) and seismic waves at the first registration point,

Δt ₄ is the time interval between the arrival of EMP (light) and seismic waves at the second registration point,

V ₂ - the specified speed of seismic waves along the paths from the signal source to the registration points.

From the updated speed of the seismic waves and the time intervals between the arrival of the EMP (light) and the seismic waves at the registration points, the determined values A, B and the specified location of the signal source are determined.

When the signals of the sources of low-frequency EMR appear, the currents induced in the second block of low-frequency magnetic antennas 7 from the signal source, through the first block of amplifiers 8 and the first block of the ADC 22, enter the PC 1.

The received signals of a pair of orthogonal antennas from the second block of low-frequency magnetic antennas 7 installed at the observation point in the horizontal plane so that one of the two antennas is oriented by the maxima of the radiation pattern in the direction from one registration point to another registration point, are used to determine by known methods [3] angle α _{1 of the} arrival of the low-frequency EMR signal to the observation point, i.e. the angle between the direction from one registration point to another registration point and the direction from the observation point to the source of low-frequency EMR signals, for example, by the formula

,

,

where A ₉ , A ₁₀ are the amplitudes of the medium-frequency signals arriving at the PC 1 from the first ADC block 22 from low-frequency antennas of the observation point placed in the horizontal plane, and A ₁₀ is the amplitude of the signals from the antenna oriented by the maxima of the radiation pattern in the direction from one point registration to another registration point. At the same time, the signals of low-frequency orthogonal antennas from the outputs of the first block of amplifiers 8 are fed to the first threshold block 9. When the signals exceed the values specified by the PC 1, logical units are generated at the outputs of the first threshold block 9 and fed to the first block of OR circuits 10, the output signal of which triggers the first , second and third timers 11, 45, 57. The output signal of the first timer 11 allows the passage of pulses from the first clock generator 21 through the first circuit And 12 to the first block of counters 13 and prepares the first block to the AND circuits 20, followed by zeroing counters expected to block or signal the arrival. The output signals of the second and third timers 45, 57 allow the passage of pulses from the second clock generator 66 through the third circuit AND 46 to the counter 47 and prepare the second circuit And 44, as well as through the fourth circuit And 58 to the second counter 59 and prepare the second circuit And 56 with subsequent expected zeroing of the counters or with the arrival of signals. Thus, the countdown starts from the moment of arrival at the observation point of low-frequency electromagnetic radiation (EMP) to identify a registered phenomenon, for example, a magnetic storm.

The temperature increase associated with the release from the nuclear power plant is recorded by the block of temperature detectors 17, which are uniformly spaced at the observation point at a circumference in a horizontal plane at 2n (n≥2) points. The signals from the outputs of the block of temperature receivers 17 through the second block of amplifiers 18 and the first block of the ADC 22 are supplied to the PC 1. In addition, the output signals of the block of temperature receivers 17 through the second block of amplifiers 18 are fed to the second threshold block 19. If the signal exceeds the values specified by the PC 1, at the outputs of the second threshold block 19, logical units are formed that arrive at the first block of And 20 circuits, the output signals of which, if there is a logical unit coming from PC 1 at the third inputs of the first block of And 20 circuits, stop the first block counters 13 and fixed intervals of time between the moment increase background radiation at the observation point and the temperature increase in each of 2n temperature receivers. If there is no temperature increase, the first block of counters 13 stops and resets after the end of the signal of the first timer 11.

The obtained values of the time intervals from the outputs of the first block of counters 13 go to a personal computer 1, where the position of the receivers corresponding to the minimum of 2n time intervals determines the approximate direction to the emission source, the maximum difference in the moments of temperature increase at diametrically opposite temperature receivers and the known distance between them the velocity of temperature disturbance is determined, and from the obtained velocity of movement and the minimum of 2n time intervals is determined rientirovochnaya range to the emission source.

To register signal sources that are not accompanied by fast signals (career or underground explosions, explosions in buildings, etc.), the device provides an estimate of the distance to the signal source from the difference in the arrival time of slow signals, for example, seismic signals and infrasound:

;

,

;

,

where S is the distance from the registration point to the signal source;

t ₁ - time of arrival of infrasound;

t ₂ is the arrival time of seismic signals;

Δt ₅ is the difference in time of arrival of infrasound and seismic signals;

v ₁ is the speed of infrasound;

v ₂ - speed of seismic signals

To do this, the signals from the output of the seismometer 40 enter through the first amplifier 3, the first filter 4, the third amplifier 41 and the second filter 42 to the second threshold element 43. When the signal exceeds the value specified by the PC 1, a logical unit is formed at the output of the second threshold element 43 in PC 1 and to the OR circuit 67, the output signal of which starts the third timer 57. The output signal of the third timer 57 allows the passage of pulses from the second clock generator 66 through the fourth circuit And 58 to the second block of counters 59 and prepare the second block of circuits AND 56, to the second inputs of which a signal from the fifth timer 65 is received, which forms a time window by a command from PC 1. Thus, the time starts from the moment seismic signals arrive at the observation point.

The infrasound wave accompanying this phenomenon is received by the blocks of microbarometers 50 of the first and second channels, the output signals of which are supplied to the PC 1 through the seventh amplifier block 51, the third filter block 52 and the second ADC block 61. In addition, the output signals of the microbarometer block 50 are received through the eighth amplifier block 53 and the fourth filter block 54 to the fifth threshold block 55. When the signal exceeds the value specified by the PC 1, logical units are generated at the outputs of the fifth threshold block 55 and fed to the second block of AND 56 output circuits dnye signals which, in the presence of an enable signal at the third input of the fifth timer 65 is stopped by the second counters 59 and counters unit detects time intervals between the arrival of the seismic signals and infrasound the first and second point registration. In the absence of an infrasound signal, the second block of counters 59 is stopped and reset after the end of the signal of the third timer 57.

The obtained values of 2m time intervals from the output of the second block of counters 59 go to a personal computer 1, where the distance from the recording points to the signal source, as well as the position of the microbarometers, are determined by the infrasound velocity previously measured during calibration of microbarometers and the known velocity of seismic waves , corresponding to the minimum of 2m time intervals, the approximate direction to the signal source is determined.

When fast signals (EMR, etc.) appear, preference is given to them, i.e. such a signal from the output of the first block of OR circuits 10 not only starts the timers, as indicated above, but also enters the second input of the fifth And 68 circuit, the first input of which is the logic unit from the output of the third timer 57, triggered by a signal from the second threshold block 43 and at the inverse input, a logical zero from the output of the second timer 45 (which corresponds to the event processing mode without fast signals) and generates an output signal to reset counter 47 and the second block of counters 59 to zero, as well as to bring the second and third timers 45, 57 in the initial state by entering the control inputs.

The combination of received signals entering the PC 1 from the outputs of the ADC, threshold blocks and threshold elements, is used to identify the phenomenon, for example:

- EMP or (and) flash and infrasound accompany lightning discharge;

- flash, infrasound and seismic signal accompany an open industrial explosion;

- infrasound and seismic signal accompany a quarry or closed explosion;

- an increase in the background radiation and an increase in temperature accompany emissions from nuclear power plants;

- low-frequency electromagnetic radiation in the absence of other signals accompanies magnetic storms;

- flash and infrasound accompany an open gas explosion, etc.

To prevent false stops of the counter 47 and the second block of counters 59 from later near signals that may appear during the propagation of seismic waves or infrasound, PC 1 calculates the approximate value of the range and the expected moments of arrival of seismic waves and infrasound with a margin of range estimation errors and the propagation speed of infrasound and seismic waves, and according to the readings of counter 47 and the second block of counters 59, at the right time, PC 1 opens a time window using the fourth timer 64 for walking counter stop signal 47 and opens the time window via the fifth timer 65 for the passage of the second block stop signal counter 59. If necessary, to prevent false shutdowns first block counter 13 PC 1 opens a temporary window for the passage of the stop signal when the temperature rises. To do this, using the approximate value of the range and the expected propagation velocity of the temperature perturbation in PC 1, the smallest expected time of arrival of the temperature perturbation and the corresponding readings of the first block of counters 13 are calculated, starting from which the PC 1 supports a logical unit at the third inputs of the first block of And 20 circuits.

The calculation of the approximate value of the range (if it is not known, as in the case of an ejection from a nuclear power plant) is carried out before the arrival of seismic waves and infrasound. To do this, the geometric problem of finding the sides of the triangle at two angles and the adjacent side is solved by the obtained angles of arrival of the EMR and the known distance between the registration points, i.e. the distances A, B from the registration points to the signal source are determined, and taking into account the received directions to the signal source and the distances from the registration points, the approximate location of the signal source is determined, which is then used to calculate the allowed time intervals for recording the arrival of seismic waves and infrasound in order to protect against interference coming during the passage of seismic waves and infrasound from the signal source to the observation point. For small angles close to 0 or 180 degrees, when the error of the triangulation is large, PC 1 opens a time window immediately after the arrival of the EMP, given the low probability of three events - the location of the interference source at the same small angles as the signal source, the location of the interference source closer than the signal source, and the occurrence of interference earlier than the seismic wave or infrasound from the signal source enters the zone of proximity of the interference source, however, if necessary, the calculation of the approximate range value can be carried out for low frequency electromagnetic radiation or emr small angles of arrival on the analysis of the EMR spectrum signal by a formula which takes into account the change in the spectrum of the EMR signal depending on the distance traveled [5]:

,

,

where R is the distance to the signal source,

C is the speed of light

ω ₁ , ω ₂ - respectively, the upper and lower frequencies of the spectrum of the EMP signal,

H ₁ , H ₂ - respectively, the amplitude of the signals of the lower and upper frequencies of the EMP signal.

When noise appears that does not clog the entire operating frequency range, in PC 1, according to the results of preliminary frequency analysis, control signals are generated for the ranges of EMP, light, temperature, seismic and infrasound signals separately, which are fed to the control inputs of the first and second filter units 25, 30, to the control inputs of the first and second filters 4, 42 of the seismic signal range, as well as to the control inputs of the third and fourth filter blocks 52, 54 of the infrasound signal range and using digital potentiometers in cut out from the passband sections of the interference frequency.

To protect against false signals (for example, solar flare, temperature changes, long-term EMP signals, etc.), the PC 1 periodically polls all EMP receivers, light, temperature, infrasound and seismic oscillations (from the outputs of the corresponding ADCs and ADC units 22, 60, 61 , 62, 63) and sets for each signal receiver the response thresholds of the corresponding threshold elements and threshold blocks, i.e. takes into account changes in background signals.

The required amplitude and phase ratios of the signals are generated using PC commands 1 received at the control inputs of the first, second, third, fourth, fifth, sixth, seventh and eighth blocks of amplifiers 8, 18, 24, 26, 29, 31, 51, 53, as well as to the control inputs of the first, second and third amplifiers 3, 15, 41 (for example, using digital potentiometers).

These modes of operation of the device can be implemented simultaneously in different combinations, using a separate control for each amplifier, filter and threshold element.

To control the amplifier-converter paths, calibration signals are provided to the first block of magnetic antennas 2 from the first block of calibrators 35 controlled by the PC 1 using the first DAC unit 34, calibration signals to the block of light sensors 23 from the second block of calibrators 37 controlled by the PC 1 s using the second block of the DAC 36, as well as applying calibration signals to the seismometer 40 from the first calibrator 39 controlled by the PC 1 using the first DAC 38. The calibration of the block of microbarometers 50 is carried out using the second about calibrator 49. The second calibrator 49 is a source of pulsed and sinusoidal infrasound controlled from a PC 1 using the second DAC 48, in the simplest case it can be a power amplifier with a dynamic loudspeaker. The second calibrator 49 is installed at a distance of several meters from the block of microbarometers 50 and is acoustically connected to the latter through the environment. During the calibration, the amplitude-frequency characteristics (AFC) of the block of microbarometers 50 with the seventh block of amplifiers 51 and the third block of filters 52 are determined, as well as the speed of infrasound at the current moment. For this, the PC 1 is stored in the memory digital images of the reference sinusoidal signals and the pulse signal, which are transferred from the PC 1 to the second calibrator 49 through the second DAC 48. To remove the frequency response to the microbarometer block 50 from the second calibrator 49, reference sinusoidal acoustic signals with frequencies of the operating range are supplied microbarometers, which are converted, amplified, filtered, and through the second block of the ADC 61 enter the PC 1, where the frequency response is calculated. To determine the speed of infrasound, the PC 1 currently supplies a reference pulse signal to the second calibrator 49 and simultaneously starts the fifth timer 65, and through the third timer 57 starts the second block of counters 59, which starts counting the infrasound time for the known distance between the second calibrator 49 and the block of microbarometers 50. The output signal of the block of microbarometers 50 through the seventh block of amplifiers 51, the third block of filters 52, and also through the eighth block of amplifiers 53 and the fourth block of filters 54 is fed to the fifth threshold The new block 55 and the second block of circuits AND 56 stop the second block of counters 59. The obtained values of the time intervals from the outputs of the second block of counters 59 are sent to PC 1, where the infrasound speed at the current moment is determined from the known distances between the second calibrator 49 and the block of microbarometers 50 calculating the distance to the signal source.

The amplification-conversion paths of the low-frequency EMR, temperature and radiation signals are monitored by applying signals from autonomous signal simulators installed in the sensitivity zone of the block of low-frequency magnetic antennas, temperature receivers, and a radiation receiver.

Information obtained in the process of work is tied to a single time using block 5 of a single time system (GPS or Glonass), and transmitted to the destination using block 6 communication with subscribers.

Thus, the proposed device for determining the location of the signal source in comparison with the prototype provides the possibility of bearing several types of signal sources, reducing errors when using the device at short distances and increasing the noise immunity of the device.
