Description

Technical Field

[0001] The invention relates to the technical field of target calibration, in particular to a portable photoelectric target calibration device. Background Art

[0002] At present, infrared guidance technology has developed from point source guidance to infrared focal plane imaging guidance, and the attack capability and anti-interference capability of its guided missiles have also been greatly enhanced, which poses a huge threat to military helicopters that mainly undertake low-altitude missions such as ground attack, fire support, battlefield reconnaissance, and emergency rescue.

[0003] To improve helicopter survivability, helicopters are beginning to be equipped with missile approach warning devices and laser directional jammers. The missile approach warning device detects incoming missiles and simultaneously guides the laser directional jammers to precisely jam them. To achieve this, the missile approach warning device and laser directional jammers require precise calibration after installation.

[0004] Currently, missile approach warning devices and laser directional jammers are often calibrated using flight tests. However, this calibration method relies on a real flight environment, resulting in the following problems: First, the calibration process is time-consuming and labor-intensive, with high calibration costs. Second, the real flight environment contains multiple uncertainties, which can affect the calibration results, resulting in low accuracy. Therefore, it is necessary to invent a portable optoelectronic calibration device to address the time-consuming and labor-intensive calibration process, high calibration costs, and low accuracy of the existing methods for calibrating missile approach warning devices and laser directional jammers. Summary of the Invention

[0005] In order to solve the problems of time-consuming and labor-intensive calibration process, high calibration cost and low calibration result accuracy in the existing target calibration methods of missile approach warning devices and laser directional jamming equipment, the present invention provides a portable photoelectric target calibration device.

[0006] The present invention is achieved by adopting the following technical solutions:

[0007] A portable optoelectronic target calibration device comprises a case, an aiming mechanism, an infrared radiation mechanism, an electric baffle mechanism, a laser detection mechanism, a lithium battery module, a power management module, and an integrated processing module; the aiming mechanism is mounted on the outer top wall of the case; the infrared radiation mechanism is installed through the front wall of the case, with the radiation end of the infrared radiation mechanism facing forward; the electric baffle mechanism is installed through the front wall of the case, and the electric baffle mechanism can be opened to shield the radiation end of the infrared radiation mechanism; the laser detection mechanism is installed through the front wall of the case, with the detection end of the laser detection mechanism facing forward; the lithium battery module, the power management module, and the integrated processing module are all mounted in the inner cavity of the case; the output end of the lithium battery module is connected to the input end of the power management module; the output end of the power management module is respectively connected to the power supply end of the infrared radiation mechanism, the power supply end of the electric baffle mechanism, and the power supply end of the laser detection mechanism; the output end of the laser detection mechanism is connected to the input end of the integrated processing module; the output end of the integrated processing module is connected to the control end of the electric baffle mechanism.

[0008] The specific usage process is as follows: First, the device (i.e., the portable optoelectronic target calibration device described in the present invention) is set up on the ground within an airport using a tripod. The aiming mechanism is then used to adjust the device's orientation so that it aligns with the missile approach warning device on the target helicopter. A threshold for successful laser jamming is then set, and the infrared radiation mechanism, electric shutter mechanism, and laser detection mechanism are powered on. At this point, the infrared radiation mechanism emits high-intensity medium-wave infrared light. The integrated processing module controls the electric shutter mechanism to swing back and forth, alternating the infrared radiation mechanism's radiation end open and closed, thereby simulating the infrared radiation characteristics of an incoming missile. After the missile approach warning device detects the infrared radiation characteristics of the incoming missile, it reports the device's azimuth and pitch angles in the target helicopter's coordinate system to the laser directional jamming device on the target helicopter, which then emits a laser beam. When the missile approach warning device guides the laser directional jamming device with the required accuracy, the laser beam emitted by the laser directional jamming device will fall on the device, thereby being detected by the laser detection mechanism. At this point, the laser detection mechanism's output signal contains information about the laser beam. The integrated processing module extracts this information (frequency, irradiation power, and duration) from the laser detection mechanism's output signal and compares it with the threshold for successful laser jamming. This information then indicates that the laser jamming was successful. If the missile approach warning device's guidance of the laser jamming device fails to meet the required accuracy, the laser beam emitted by the laser jamming device will deviate from the device and thus go undetected by the laser detection mechanism. In this case, the laser detection mechanism's output signal lacks information about the laser beam, and the integrated processing module is unable to extract this information from the laser detection mechanism's output signal. Consequently, the integrated processing module indicates that the laser jamming was unsuccessful, prompting the operator to modify the laser jamming device's installation parameters until the integrated processing module indicates that the laser jamming was successful. During this process, the lithium battery module supplies power to the infrared radiation mechanism, the electric baffle mechanism, and the laser detection mechanism through the power management module.

[0009] Based on the above process, compared to the calibration methods of existing missile approach warning devices and laser directional jamming equipment, the portable optoelectronic calibration device described in the present invention does not require a real flight environment and can be calibrated on the ground within an airport. This has the following advantages: First, the calibration process is time-saving and labor-saving, and the calibration cost is lower. Second, the influence of various uncertain factors on the calibration results is avoided, thereby achieving higher accuracy of the calibration results.

[0010] Furthermore, the inner cavity of the box is provided with a partition, and the partition divides the inner cavity of the box into a front chamber and a rear chamber; the lithium battery module, the power management module, and the integrated processing module are all installed in the rear chamber; the rear wall of the box is penetrated by a power supply interface, three switch buttons, a touch screen, and a communication interface; the power supply interface is connected to the input end of the lithium battery module; the three switch buttons are connected in series one by one to the power supply circuit of the infrared radiation mechanism, the power supply circuit of the electric baffle mechanism, and the power supply circuit of the laser detection mechanism; the touch screen and the communication interface are both bidirectionally connected to the integrated processing module; an air outlet is opened through the top wall of the box; an air inlet is opened through the bottom wall of the box; a DC fan is installed on the inside of the air outlet; dust covers are installed on the outside of the air outlet and the inside of the air inlet; a tripod threaded interface is opened on the outer bottom wall of the box; and handles are installed on the left outer wall and the right outer wall of the box.
