Description

The proposed utility model relates to passive aiming devices intended for installation on sniper rifles and machine guns of normal caliber with side mounting. The sight can be used to monitor the battlefield, detect, recognize and measure the range to sounding targets, conduct targeted shooting at any time of the day, in conditions of poor visibility.

Known night vision sights, the principle of operation, which is based on functioning in conditions of natural night illumination and amplification of the low-brightness image created by the lens on the photocathode of the electron-optical converter, into an image sufficient in brightness for the operator to examine through the eyepiece. Structurally, the sights consist of three modules: a lens, a body and an arm for mounting on weapons [1, 2]. The range of target recognition when using the sight for its intended purpose substantially depends on the level of natural night illumination, the transparency of the atmosphere and the “target-background” contrast. With low light, poor atmosphere transparency, low cloud cover, the location of the target on a dark background, the recognition range decreases. In addition, the noise immunity of night vision sights with an electron-optical converter is characterized by a strong influence of light interference.

These external factors have little effect on thermal imaging sights. The principle of operation of the sight is based on the conversion of the intrinsic infrared radiation of the target and background in the spectral range of 8 ... 14 μm into a visible image observed by the operator on the screen of the micro-display through the eyepiece.

The closest, in its technical essence to the claimed utility model, is a thermal imaging sight [3], selected for the prototype. Structurally, the sight consists of a body, a lens, an eyepiece with an eyecup and an arm. The optical parts of the lens and eyepiece are in their own frames, connected to the housing by threaded connections. A thermal radiation receiver is placed in the sight housing - a microbolometric matrix with power boards, image signal processing, sighting network and service information, microdisplay, battery compartment, monitor connector. On the top of the sight housing is a panel with control buttons.

The range to the goal is determined in a passive way that implements the principle of "base on the goal." The rangefinder scale, designed for the height of a typical target (growth figure) 1.7 m, is designed to determine the range from 400 to 800 m.The numbers on the scale correspond to distances of 400, 600 and 800 m.The accuracy of determining the distance to the target does not exceed 15%. The scope does not implement the function of measuring range by the sound of a shot [4] taking into account the firing conditions (pressure, temperature, resulting wind speed).

The disadvantages of the prototype are a limited number of typical targets for measuring range, low accuracy of its determination. The objective of the proposed utility model is to increase the number of typical targets for measuring range through the use of a sound rangefinder channel and to increase the accuracy of determining the range, which, combined with data on the ambient temperature, the resulting wind speed and processing of data on a microprocessor for automatic aiming corrections, will allow accurate shoot to kill.

The solution to this problem is proposed to be carried out using a thermal imaging and sonic sight, which, like the sight selected as a prototype, consists of a housing, a lens, an eyepiece with an eyecup and an arm, a microbolometric matrix with power boards, image signal processing, and aiming shaping are placed in the housing grid and service information, microdisplay, battery compartment, monitor connector, a panel with control buttons is located on the top of the case.

A feature of the proposed sight, which distinguishes it from the known one, is that a sound rangefinder with temperature and wind sensors for measuring the distance to the sounding target, including a microphone capsule with a directional antenna for converting acoustic signal to electric, amplifier and microcontroller as part of an analog-to-digital converter, storage device, microprocessor, time meter GOVERNMENTAL intervals node receiving and outputting data.

The essence of the utility model is as follows. The installation of a sound imaging rangefinder channel (ZDK) to measure the range to the sounding target allows you to increase the number of typical targets for measuring range and improve the accuracy of determining range by determining the conditions for firing. Thus, a solution to the problem is provided.

The proposed thermal imaging and sonic sight is illustrated by the drawings shown in FIG. 12.

The sight consists of a housing 7 of a thermal imaging channel (Fig. 1), a lens 2, an eyepiece with an eyecup 3 (Fig. 1, 2) and an arm 4 (Fig. 2), a microbolometric matrix 5 with power cards 6, signal processing is placed in the housing 7 image 7, the formation of the reticle and service information 8, microdisplay 9, a time interval meter (IVI) 24 (Fig. 1), a compartment for batteries 10, a connector for connecting a monitor 77, a temperature sensor 25 is fixed at the bottom of the case, on the top part of the housing is a panel with control buttons 12, the sensor in tra 26 (FIG. 2). To the housing 7 (Fig. 1) of the thermal imaging channel by a fixed detachable connection with the use of running bolts 13, the case of the directional receiving antenna 14 of the ZDK is fixed. To reduce the reflection of sound from the walls, the inner surface of the case is covered with sound-absorbing material 15. Inside the case there is a microphone capsule 16, which is attached to the case by a threaded ring 17 and posts 18. An amplifier 19 is mounted near the capsule, which is electrically connected to the analog-to-digital converter 20 and the microcontroller 21 . The back side of the case 14 is closed by a cover 22, on which the matching unit 23 is fixed. The matching unit 23 is electrically connected to the reticle and service information board 8 te plovizion channel and IVI 24 (Fig. 1).

Thermal imaging sound works as follows. The channel case of the sound range finder (Fig. 1) is fixed to the housing of the thermal imaging channel of the sight so that the directivity axis of the ZDK is parallel to the optical axis of the thermal imaging channel. The parallelism of the axes is provided by adjusting the position of the case ZDK using the running bolts 13.

A verified sight with a power source in the compartment 10 using the device 4 is installed on the weapon. When you turn on the power of the sight on the panel 12, the own radiation of the object space generated by the lens 2, falls on the microbolometric matrix 5 and is converted into an electrical signal. In the devices of the image signal processing board 7, the electrical signal is amplified and converted into a video signal, and an aiming grid and service information are formed in the device 8. Information from device 8 and a visible image of the space of objects are displayed on the microdisplay 9. In the center of the microdisplay, an aiming mark is displayed that can be adjusted in color (black / white) and in position, which is aligned with the axis of the barrel of the weapon. Observing through the eyepiece 3, the operator studies the phono-target environment, searches for the target. If the target unmasks itself with a shot, then the intense optical signal enters the thermal imaging channel, is processed in the device 7, and the START signal is generated to start the time interval meter 24 (Fig. 1). The sound signal of the delayed shot is received by the directional antenna 14, 15, the acoustic capsule 18 is converted to analog electric and amplified to 19, converted to digital to 20, which is processed in the microcontroller 21 and the STOP signal is generated. The time meter measures the lag time in digital format. The digital signals of IVI 24, temperature sensors 25 and wind 26 are transmitted to the microcontroller of the device for forming reticle and service information 8. In the microcontroller of device 8, the built-in software calculates the range in terms of the delay time taking into account the parameters of the propagation medium of the sound signal and the aim angle taking into account the corrections for deviation of temperature, speed and wind direction. In accordance with the aiming angle, the position of the aiming mark on the micro-display 9 is set.

The image of the target, the position of the aiming mark, as well as service information (measured range, aiming angle, type of ammunition, etc.) are displayed on the micro-display and also transmitted to external devices 11 (Fig. 2). The operator combines the reticle with the aiming point on the target and fires a shot.

Thus, the proposed thermal imaging and sound sight allows you to use it as a passive-action aiming device mounted on sniper rifles and machine guns of normal caliber.
