Description

The proposed utility model relates to multichannel passive-action portable devices designed for combined arms and artillery reconnaissance of sounding targets day and night in the conditions of optoelectronic counteraction. The intended use of the device can be made both without installing an optoelectronic module on the guidance mechanism and tripod, or using the guidance mechanism and tripod.

Known optoelectronic sound metering system for passive reconnaissance (1B75), which includes several sound receivers mounted on the surface of the earth, and an optoelectronic module operating both in the infrared and in the visible spectrum of optical radiation [1]. The optoelectronic module contains six television and six thermal imaging cameras, which are located on a telescopic telescopic rod. Optical-electronic and sound-measuring devices of the complex can be used as intended at any time of the day for reconnaissance of the firing positions of the receiver and rocket artillery, as well as anti-aircraft and tactical missiles. The mass and overall dimensions of the devices do not allow their use as portable, they are placed on the chassis of the KamAZ-6350.

The Owl automated reconnaissance system for acoustic reconnaissance, which can be built in a monoblock scheme (one antenna device) and a distributed scheme (four antenna devices), has reduced mass and dimensions. Structurally, this is a hardware-software module containing sensitive acoustic sensors and a computer. Sensors provide reception of an acoustic signal in azimuth of 360 °. The sound wave from the target is received by acoustic sensors and the coordinates of the sounding target are calculated by the difference in travel time. Special software processes acoustic information, filters out noise interference, for example, the sound of a running engine, an explosion, etc.

Known acoustic electronic module PEARL [2]. It is a single-case device that includes a miniature acoustic matrix of sensitive elements with integrated electronics, an integrated processor unit with a gyrometer and a human-machine interface showing the direction of the shot in azimuth and elevation using LEDs.

The closest, in its technical essence to the claimed utility model, is the optoelectronic module of portable reconnaissance devices 1PN142, 1PN143 [3,4]. The intended use of the devices is possible “with hands” (without installing an optoelectronic module on the guidance mechanism and tripod) and using a tripod and a biaxial rotary guidance mechanism (to increase the accuracy of guidance and determine coordinates when working on small targets at long ranges). In addition, it is possible to install the optoelectronic module on the PAB-2M compass via the bracket and on the angle-measuring device of the laser reconnaissance device LPR-1 (LPR-2) without additional devices.

To ensure the observation, search, recognition and determination of target coordinates at any time of the day, the optoelectronic module contains a housing, thermal imaging, television and laser rangefinder channels, a video processor board, devices (information management and processing; radio navigation, storage, video viewing) fixed in the housing , electronic compass and battery pack.

The disadvantage of the prototype is the presence of a laser rangefinder channel that implements a pulsed active method of measuring range, which does not ensure stealth, allows the enemy to quickly determine its location and effectively counter it using a laser radiation sensor, this makes it difficult to use the prototype as a module of a portable passive reconnaissance reconnaissance device. The objective of the proposed utility model is the implementation of a passive method of measuring range to the target to ensure the secrecy of the functioning of the reconnaissance device.

The solution to this problem is proposed to be carried out using an optoelectronic module, which, like the module selected as a prototype, consists of thermal and television channels, a video processor board and a storage device, information management and processing devices, a video viewing device, and a battery pack for monitoring , search and recognition of targets in the visible and infrared ranges at any time of the day, a radio navigation device and an electronic compass for orientation and determination of ordinates of its location.

A feature of the proposed optoelectronic. The module that distinguishes it from the known device is that instead of a laser rangefinder channel, a passive directional acoustic sensor is installed in the housing for measuring the distance to the sounding target, including a microphone capsule with a directional antenna for converting the acoustic signal into an electric signal, an amplifier and a microcontroller composed of analog - a digital converter, a storage device, a microprocessor, a time interval meter, a data receiving and output unit.

The essence of the utility model is as follows. The introduction of a directional acoustic sensor (NAD) instead of a laser rangefinder channel to measure the distance to the sounding target allows you to determine the coordinates of the target using a passive method. Thus, a solution to the problem is provided.

The proposed optoelectronic module is illustrated by the drawings shown in FIG. 1 and FIG. 2. In FIG. 1 shows the design of a directional acoustic sensor. In FIG. 2 presents a structural diagram of the proposed utility model.

The design of the acoustic sensor is shown in FIG. 1. The carrier element is a tubular case 7. To reduce the reflection of sound from the walls, the case is covered with sound-absorbing material 2. Inside the case there is a microphone capsule 3, which is attached to the case by a threaded ring 4 and posts 5. An amplifier 6 is mounted near the capsule, which is electrically connected to the microcontroller 7 and a time interval meter 8. The back of the case 1 is closed by a cover 9, on which the output connector 10 is fixed.

The optoelectronic module operates as follows. way. A directional acoustic sensor (Fig. 1) is mounted directly in the module housing of a portable passive reconnaissance device so that its directivity axis is parallel to the optical axes of the thermal and television channels. The parallelism of the axes is provided by adjusting the position of the microfone capsule 3 with the help of a threaded ring 4 and racks 5.

The current image of the space of objects from the output of the television or thermal imaging channels is fed to the video processor board, where the video signal is converted into a visible image and displayed on two microdisplays of a binocular video viewing device (Fig. 2). Watching through the video viewing device of the optoelectronic module, the operator studies the phono-target environment, makes detection, recognition of the target. In the center of the video viewing device, an aiming mark is displayed, adjustable in color (black / white) and in position, which is aligned with the sighting axis of the directional acoustic sensor.

By controlling the guidance mechanism, the operator combines the image of the target with the reticle. When aiming the mark on the target, the directional axis of the acoustic sensor will also coincide with the selected target. When fired, an intense optical signal enters the television or thermal imaging channel, is processed in the video processor board, and a “START” signal is generated to start the time interval meter 8 OVER (Fig. 1). The sound signal of the delayed shot is received by the directional antenna 1,2 of the acoustic capsule 3, amplified 6, converted to digital, which is processed in the microcontroller 7 and the signal "STOP" is generated. The time meter measures the lag time in digital format. The digital signal through the output connector 10, mounted in the cover 9, is transmitted to the control and information processing device (Fig. 2) of the module.

The built-in software calculates the delay time range taking into account the parameters of the propagation medium of the audio signal, calculates the target coordinates, automatically monitors the health of the components of the optoelectronic module when the power is turned on and in the process of using the device for its intended purpose, automatically calibrates NAD to compensate for background noise.

The image of the background-target situation, as well as service information (measured or recorded in the memory device coordinates of the sighted targets, operating modes, etc.) are displayed on the microdisplays of the video viewing device and also transmitted to external devices (intelligence, control and communications complex (KRUS ) "Sagittarius" and others) on the interface channels RS-232, USB 2.0 (Fig. 2).

Thus, the proposed optoelectronic acoustic module allows you to use it as the basis of a portable passive reconnaissance device.
