In this particular embodiment: the infrared assembly is specifically used for focusing the infrared radiation of a target onto a sensitive element of an infrared uncooled focal plane detector by using an infrared objective lens assembly, and generating an electric signal through thermoelectric conversion; performing analog-to-digital conversion on the electric signal to convert the electric signal into a digital image signal; and carrying out non-uniformity correction, blind pixel substitution, image enhancement, brightness contrast adjustment and menu interface information superposition processing on the digital image signal to obtain the infrared image.
The working principle of the infrared assembly is as follows: the infrared radiation of the target is focused on a sensitive element of an infrared uncooled focal plane detector through an infrared objective lens assembly, and a processable electric signal is generated through thermoelectric conversion; the core circuit board performs analog-to-digital conversion on the electric signal and converts the electric signal into a digital image signal; and then carrying out non-uniformity correction, blind pixel substitution, image enhancement, brightness contrast adjustment and menu and interface information superposition and outputting on the digital image signals, and assisting an operator to realize accurate shooting.
In this particular embodiment: the laser assembly is specifically configured to emit an invisible laser pulse with a laser; collecting scattered light of laser pulses by using a sampling prism while the laser pulses are emitted to serve as reference information, sequentially carrying out filtering, photoelectric conversion and amplification and shaping on the reference information, sending the reference information to a time measuring system, and triggering the time measuring system to start timing; receiving laser pulses reflected back by a target, sequentially carrying out filtering, photoelectric conversion and amplification shaping on the laser pulses reflected back by the target, sending the laser pulses into the time measuring system, and triggering the time measuring system to stop timing; and calculating the distance of the target according to the time timed by the time measuring system and the propagation speed of the laser pulse.
The laser adopts invisible light wave band, and makes use of the superior coherence and collimation of the laser to ensure that the light spot of the laser coincides with the mechanical division of white light, thereby realizing the observation and aiming effect of the laser.
The principle of the pulse distance measurement method is that the distance is calculated by measuring the time of the laser beam in the round-trip propagation on the distance to be measured, and the formula is as follows: and L is ct/2.
In the formula, L is a distance to be measured; c is the speed of laser propagation in the atmosphere; and t is the round-trip propagation time of the laser on the distance to be measured. Here, c is the known quantity and t is the quantity to be measured. The working process of the laser pulse distance measuring machine is roughly as follows: when the laser assembly is aligned with the target, the laser emits a very strong, narrow pulse of light. When the pulse is emitted, a tiny part of light is collected by the sampling prism to be used as an emission reference signal for calibrating the time of emitting the laser. After the reference signal enters the receiving telescope, the reference signal passes through the optical filter and reaches the photoelectric converter to be converted into an electric signal, and the optical pulse is converted into an electric pulse. The electric pulse is sent to a time measuring system after being amplified and shaped, and timing is started. The light pulse emitted to the target is reflected by the diffuse reflection of the target, part of the light is reflected from the original path and enters a receiving telescope, and the light pulse passes through a filter, a photoelectric converter and an amplifying and shaping circuit and then enters a time measuring system, and the timing is stopped. The laser round-trip time can be obtained and substituted into a formula to calculate the distance.

In the shooting process, the bomb can receive the influence of factors such as weight, wind direction and the like in the moving process, the bullet drop point can deviate from the view point seen by the screen, the automatic shooting purpose is realized by integrating the influence of various external factors, and the shooting direction is adjusted, so that the drop point of the bomb finally drops on an object to be shot.
The motion of the bomb is influenced by gravity, air temperature, air pressure, altitude, wind direction, wind speed, and the characteristics of the bomb itself. Because different bombs are affected differently by different external environments, different shooters exist for different types of bombs.
