Description

Technical Field

[0001] This invention belongs to the field of anti-drone technology, and in particular relates to a portable laser anti-drone system and its working method. Background Technology

[0002] "Low, slow, and small" targets, such as drones, loitering munitions, and micro-aircraft, are characterized by low-altitude / ultra-low-altitude penetration, slow hovering, and small size. Traditional air defense systems face significant challenges in countering them due to their high cost and difficulty. For example, these targets typically fly at extremely low speeds, making them susceptible to interference from complex ground clutter, hindering timely detection by traditional air defense radar. Furthermore, their small size presents challenges in terms of timely detonation of fuses during missile encounters. Secondly, the increasing cost of drones, coupled with the rising performance of existing air defense weapons, creates a significant cost asymmetry when using traditional missile-based anti-drone systems, resulting in high costs. As the confrontation between drones and anti-drone systems intensifies, a low-cost, high-precision detection and tracking technology is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide a low-cost, highly accurate, portable laser anti-nuclear system and its operating method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A portable laser anti-munition system includes: a detection and tracking unit for searching, detecting, tracking, and identifying "low, slow, and small" targets; the detection and tracking unit includes an infrared detection and tracking module for identifying the target type based on the infrared characteristics of the target and performing target search and tracking; a visible light detection and tracking module for identifying the target type based on the shape and color characteristics of the target and performing target search and tracking; a visible light precision tracking module for performing target search and tracking based on angle information provided by the infrared detection and tracking module and the visible light detection and tracking module; and a laser ranging module for distance measurement; and a laser destruction unit for generating a high-energy laser beam to destroy the target, the laser destruction unit including... The system includes multiple wind-cooled laser sources, a beam spatial energy synthesis module, and a beam positioning module. Laser beams emitted from the multiple wind-cooled laser sources are converged by the beam spatial energy synthesis module. The beam positioning module emits high-energy laser beams from the beam spatial energy synthesis module at the same angle based on the target angle information provided by the detection and tracking unit. The beam focusing distance is matched according to the target distance to achieve laser damage to the target. A control unit guides the detection and tracking unit to track the target and controls the laser damage unit to damage the target. A support unit provides power and timing / positioning for the detection and tracking unit, the laser damage unit, and the control unit.

[0006] Furthermore, the wavelength interval of the air-cooled laser source is not less than 10 nm.

[0007] Furthermore, the control unit includes an equipment monitoring module, a detection and tracking control module, a laser control module, a damage assessment module, an external information receiving module, and a situation display module. The equipment monitoring module is used to monitor the working status of each unit, the detection and tracking control module is used to control the operation of each module of the detection and tracking unit, the laser control module is used to control the laser damage unit to accurately damage the target, the damage assessment module is used to determine whether the target has been damaged, and the external information receiving module is used to receive rough external information about the target sent from the external network and convert it into angle, distance, speed, and type information of the laser anti-radio system deployment location.

[0008] Furthermore, the protection unit includes an energy storage battery module, which provides instantaneous high-power DC power to the air-cooled laser source, and each air-cooled laser source is configured with one energy storage battery module.

[0009] Furthermore, the protection unit also includes a direct power supply module, a timing and positioning module, and a high-precision turntable. The direct power supply module supplies power to the energy storage battery module, the timing and positioning module provides timing and positioning for the laser anti-radiation system, and the tracking and detection unit and the laser destruction unit are mounted on the high-precision turntable.

[0010] The present invention also provides a method for operating a portable laser anti-radiation system, comprising the following steps:

[0011] S1. After powering on and completing timing and positioning, the control unit receives rough external information about the target from the external network and converts it into information about the angle, distance, speed, and type of the laser anti-radio system deployment location.

[0012] S2. For a target to be destroyed, the control unit sends rough external information of the target to the infrared detection and tracking module and the visible light detection and tracking module. The infrared detection and tracking module and the visible light detection and tracking module search for and track the target. When either the infrared detection and tracking module or the visible light detection and tracking module searches for and tracks the target, the other module simultaneously searches for and tracks the target to confirm its position, and outputs the target's angle information based on the center point position of the tracked target, and sends it to the control unit.

[0013] S3. The control unit determines whether the laser anti-nuclear system has the ability to kill the target based on the target type. If it does, it guides the visible light precision tracking module to search and track the area near the angle information output in step S2. When the visible light precision tracking module tracks the target, it outputs the high-precision angle information of the target and sends it to the control unit. If it determines that the laser anti-nuclear system does not have the ability to kill the target, it abandons the target, returns to step S2, and tracks the next target.

[0014] S4. After receiving the high-precision angle information sent by the visible light precision tracking module, the control unit controls the laser ranging module to measure the target distance and superimposes the high-precision angle information to form the target's high-precision azimuth, elevation, and distance information.

[0015] S5. The control unit receives the high-precision azimuth, elevation, and distance information of the target, and selects an appropriate wind-cooled laser source to emit laser beam power according to the distance to the target and the target type. Multiple wind-cooled laser sources emit beams to the beam spatial energy combining module, and the beam spatial energy combining module combines multiple laser beams into a high-energy laser beam.

[0016] S6. The control unit controls the beam orientation module to match the beam spot focusing distance according to the distance information of the attack target, and to emit the high-energy laser beam sent by the beam spatial energy synthesis module at the same angle to damage the target according to the high-precision target angle information provided by the visible light precision tracking module.

[0017] S7. The control unit observes the damage effect on the target. If the damage effect of the laser on the target is not obvious, the control unit controls the beam orientation module to deflect the beam so that the high-energy laser beam damages different positions of the target.

[0018] S8. The control unit determines whether the target is damaged. If the target is not damaged, laser destruction continues. If the target is damaged, steps S2 to S8 are repeated to detect, track and destroy the next target.

[0019] Furthermore, in step S1, if there are multiple targets, the threats are further prioritized based on the current situation of the protected targets to determine the order in which targets should be destroyed.

[0020] As can be seen from the above technical solutions, the portable laser anti-drone system of the present invention is characterized by low cost and portability. On the one hand, it uses an air-cooled laser source, which not only significantly reduces the weight of the laser source, achieving portability, but also reduces costs. On the other hand, it uses multiple air-cooled laser sources to solve the problem of insufficient power of a single air-cooled laser source by combining the spatial energy of the laser beam. Without increasing the power of a single air-cooled laser source, it increases the output power of the entire laser anti-drone system, achieving target destruction. The portable laser anti-drone system of the present invention can be flexibly deployed, overcoming the problem that existing vehicle-mounted anti-drone systems are easily restricted by terrain and ground objects, making it difficult to deploy comprehensively. It can be deployed in key locations according to terrain features based on the possible penetration paths of drones, and can be deployed at multiple points to fill anti-drone gaps, especially suitable for mountainous terrain and other areas where vehicle-mounted anti-drone systems are difficult to deploy. The portable laser anti-drone system of the present invention can achieve light-speed strike and zero ammunition consumption. The laser beam reaches the target at the speed of light, without the need for ballistic calculations, and the energy is infinitely replenished. It can accurately destroy targets with low collateral damage. The focused high-energy beam directly burns the key components of the drone, avoiding the collateral damage problem of traditional ammunition. Attached Figure Description

[0021] To more clearly illustrate the embodiments of the present invention, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] Figure 2 This is a schematic diagram of the structure of the laser destruction unit according to an embodiment of the present invention;

[0024] Figure 3 This is a flowchart illustrating the operation of the portable laser anti-nuclear system according to an embodiment of the present invention.

[0025] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings. In the detailed description of the embodiments of the present invention, for ease of explanation, the drawings illustrating the device structure will be partially enlarged without adhering to the general scale. Furthermore, the schematic diagrams are merely examples and should not be construed as limiting the scope of protection of the present invention. It should be noted that the drawings are in a simplified form and use non-precise scales, solely for the purpose of conveniently and clearly illustrating the embodiments of the present invention. Additionally, in the description of this application, terms such as "first" and "second" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Terms such as "positive," "negative," "bottom," "upper," and "lower" indicate orientation or positional relationships based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] For the defense of "low, slow and small" targets, anti-none systems are mainly deployed in a point-like manner around the protected target. However, since "low, slow and small" targets can penetrate at extremely low altitudes, point deployment inevitably results in some 360° obstruction in certain directions. In particular, vehicle-mounted anti-none equipment can only be deployed in areas that vehicles can reach, making it difficult to overcome the impact of terrain and ground objects on target interception.

[0029] With the large-scale application of lasers in the civilian market, the cost of fiber laser sources is becoming increasingly affordable. Currently, the most common laser sources are water-cooled and air-cooled laser sources. Compared to water-cooled laser sources, air-cooled laser sources are lighter and more conducive to meeting the requirements of portable equipment. However, the continuous emission time of air-cooled laser sources is generally no more than 2 minutes, and the power of a single air-cooled laser source is difficult to achieve above 3kW, making it difficult to meet the needs of laser anti-reflection systems.

[0030] To address the problems of existing vehicle-mounted anti-gravity devices and the needs of laser anti-gravity systems, this invention proposes a portable laser anti-gravity system. It employs multiple air-cooled laser light sources for power spatial synthesis, achieving greater laser power while maintaining portability, thus meeting the requirements of laser anti-gravity. Furthermore, it can be flexibly deployed according to terrain to construct a dense laser array, forming a regional laser anti-gravity capability.

[0031] like Figure 1 As shown, the portable laser anti-munition system of this embodiment includes a detection and tracking unit, a laser destruction unit, a control unit, and a support unit. The detection and tracking unit, guided by coarse external information about the target, searches for, tracks, and identifies "low, slow, and small" targets, providing precise target guidance for the laser destruction system and offering information such as the target's angle, distance, type, and image. The detection and tracking unit can also provide real-time information about the target to be destroyed by the laser. The laser destruction unit generates a high-energy laser beam to destroy the target. The control unit, based on the received coarse external information, guides the detection and tracking unit to employ a three-class (infrared detection and tracking, visible light detection and tracking, and visible light fine tracking) two-level (coarse tracking and fine tracking) tracking mode to generate high-precision angle and distance information, controlling the laser destruction unit to destroy the "low, slow, and small" target. The coarse external information about the target is typically provided by radar, including the target's accuracy, latitude, altitude, speed, and time. The support unit provides power support for the operation of the detection and tracking unit, laser destruction unit, control unit, and other units, and provides timing and positioning for the entire system.

[0032] The detection and tracking unit in this embodiment includes an infrared detection and tracking module, a visible light detection and tracking module, a visible light precision tracking module, and a laser ranging module. The infrared detection and tracking module is used to identify the target type based on its infrared characteristics and to search for and track the target within a small range (1°–3° × 1°–3°). The infrared detection and tracking module can output high-precision angle information (0.1° × 0.1°) and has all-weather operating capabilities.

[0033] The visible light detection and tracking module is used to identify the target type based on the target's shape and color characteristics, and to search and track the target within a small range (1° to 3° × 1° to 3°), outputting high-precision angle information (0.1° × 0.1°). In some embodiments, the visible light detection and tracking module can employ a visible light detection camera, which features low cost and strong search and tracking capabilities under visually visible conditions. Combined with an infrared detection and tracking module, it can improve the detection and tracking unit's ability to detect "low, slow, and small" targets in complex environments.

[0034] The visible light precision tracking module is used to perform small field-of-view search and tracking based on the angle information provided by the infrared detection and tracking module and the visible light detection and tracking module. The tracking accuracy of the visible light precision tracking module can reach 20μm to 100μm, and it has a very high data rate, reaching over 200Hz. Its related parameters directly affect the damage effectiveness of the laser damage subsystem.

[0035] The laser ranging module is used to emit a low-power laser beam to measure the distance to "low, slow and small" targets tracked by the visible light tracking module, providing a reference for the output power and focusing distance of the laser damage unit.

[0036] like Figure 3 As shown, the laser destruction unit in this embodiment includes M air-cooled laser sources 1 (M≥2), a beam spatial energy synthesis module 2, a beam orientation module 3, and a housing 4. The air-cooled laser sources 1, beam spatial energy synthesis module 2, and beam orientation module 3 are all housed within the housing 4. Currently, the maximum power of a single air-cooled laser source on the market is 3kW, which is insufficient for the requirements of an anti-radio system. This invention employs multiple air-cooled laser sources, preferably 2≤M≤8, to generate a high-energy laser beam through beam spatial energy synthesis. Through beam spatial energy synthesis, the output power of the entire laser anti-radio system can be increased without increasing the power of a single air-cooled laser source. Moreover, with the same output power, the weight is only 1 / 2 to 1 / 5 of that of a water-cooled laser source, meeting portability requirements.

[0037] To achieve spatial energy synthesis of multiple laser light sources, the wavelength interval of each air-cooled laser light source 1 in this embodiment is no less than 10 nm. When different air-cooled laser light sources have inconsistent beam wavelengths and different reflection and refraction characteristics, the spatial energy synthesis module 2 converges the laser beam energy of multiple air-cooled laser light sources through different reflection and refraction paths. The beam direction module 3, based on the target angle information provided by the detection and tracking unit (visible light precision tracking module), emits the high-energy laser beam from the spatial energy synthesis module 2 at the same angle, and matches the beam focusing distance according to the target distance to achieve laser damage to the target. The spatial energy synthesis module 2 and the beam direction module 3 can be commercially available products; no limitation is made here.

[0038] The control unit includes an equipment monitoring module, a detection and tracking control module, a laser control module, a damage assessment module, an external information receiving module, and a situation display module. The equipment monitoring module monitors the operational status of each unit and can intervene promptly in case of malfunctions to ensure efficient and stable system operation. For example, the monitoring module can use different colors to distinguish the operational status of each unit, such as normal (green), fault (red), and degraded (yellow). The detection and tracking control module controls the operation of each module within the detection and tracking unit, providing the laser damage unit with information such as the target's azimuth, elevation, distance, target image, and target type, as well as real-time information after the target is damaged. The laser control module controls the laser damage unit (selecting an appropriate number and power) to precisely damage the target based on the battery level and the operating status of the air-cooled laser source (operating temperature, remaining emission time, etc.). The damage assessment module determines whether a target has been damaged. The system monitors the laser-damaged target through the detection and tracking unit. When an abnormality in the target's flight attitude is detected, the damage assessment module issues a damage command; otherwise, the target is considered undamaged, and the laser damage unit continues to damage the target. The external information receiving module receives coarse external information about the target from the external network, typically including the target's longitude, latitude, altitude, speed, and time. It converts this coarse external information into information such as the angle, distance, speed, and type of the laser anti-radio system's deployment location. The situation display module displays the coarse external information received by the external information receiving module, the target's angle, distance, type, and image information from the detection and tracking unit, information about the laser damage process, and information such as the laser source temperature and the duration of laser emission.

[0039] The support unit includes an energy storage battery module, a direct power supply module, a timing and positioning module, and a high-precision turntable. In this embodiment, the energy storage battery module provides instantaneous high-power DC power to the air-cooled laser source. In specific applications, the specifications and model of the energy storage battery module can be selected based on the peak power of the chosen air-cooled laser source. Using an energy storage battery module to power the air-cooled laser source significantly reduces the overall weight of the power supply compared to using a gasoline / diesel engine, achieving a lightweight portable laser anti-reflective system. For example, for a 3kW air-cooled laser source, the corresponding instantaneous power supply needs to reach approximately 10kW. A 10kW gasoline / diesel engine weighs over 80kg, while using an energy storage battery module can reduce its weight to less than 10kg. The weight of the energy storage battery module is closely related to the continuous working time of the laser source. Considering the portable design requirements, the energy storage battery module only needs to meet the peak power consumption requirement of the air-cooled laser source for 5 minutes. Each air-cooled laser source is equipped with one energy storage battery, and the energy storage battery module adopts an independent packaging design, which effectively avoids the excessive overall weight caused by multiple integrated designs, which is detrimental to portability.

[0040] The direct power supply module powers the detection and tracking unit, laser destruction unit, control unit, and support unit. When the current of the energy storage battery module drops to a certain level (70%), the direct power supply module slowly charges the energy storage battery module using AC 220V in a low-current mode. This design reduces the weight of a single energy storage battery module and also solves the problem of insufficient continuous operating time when relying solely on energy storage battery modules to power high-power air-cooled laser sources.

[0041] The timing and positioning module provides accurate time information to the detection and tracking unit, laser destruction unit, control unit, and support unit. After the system is powered on, the timing and positioning module provides time information to the detection and tracking unit and control unit. In this embodiment, the timing and positioning module includes a first timing and positioning module and a second timing and positioning module. The two modules have identical structures and functions, and are placed horizontally with a distance of at least 0.6 meters between them. The azimuth information between the two points is determined based on the azimuth difference between the two modules, serving as the azimuth information for the entire laser anti-radiation system, thus achieving the purpose of system orientation.

[0042] The detection and tracking unit and the laser destruction unit are mounted on a high-precision turntable. Through high-precision operation, the detection and tracking unit and the laser destruction unit can accurately lock onto and destroy the target in azimuth and elevation according to the indicated information.

[0043] The following is combined with Figure 3 The working process of the portable laser anti-gravity system in this embodiment will be explained. For example... Figure 3As shown, the working process of the portable laser anti-nuclear system in this embodiment is as follows:

[0044] S1. After the system is powered on, the detection and tracking unit and the control unit complete the timing and positioning. The control unit (external information receiving module) receives the external coarse information of the target sent by the external network and converts it into the angle, distance, speed, and type information of the anti-naked system deployment location. In some embodiments, the detection and tracking management module converts the received target coarse information into the angle, distance, speed, and type information of the anti-naked system deployment location (distance and speed are important bases for whether the target is within the detection range of the infrared detection and tracking module and the visible light detection and tracking module, and angle information is the central angle reference guiding the infrared detection and tracking module and the visible light detection and tracking module to search within the angle range). If there are multiple targets, the threat ranking is further performed according to the current target protection situation to determine the order of targets to be destroyed.

[0045] S2. For a target to be destroyed, the control unit (detection, tracking, and control module) sends the target's rough external information to the infrared detection and tracking module and the visible light detection and tracking module. The infrared detection and tracking module and the visible light detection and tracking module search for and track the target (coarse tracking). When either the infrared detection and tracking module or the visible light detection and tracking module searches for and tracks the target, the other module simultaneously searches for and tracks the target to confirm its location. Based on the position of the target's center point, the module outputs the target's angle information (azimuth and elevation) and sends it to the control unit (detection, tracking, and control module). The accuracy of the output angle information is around 0.1° × 0.1°.

[0046] S3. The control unit (detection, tracking, and control module) determines whether the laser anti-nuclear system has a killing capability against the target based on the target type. If so, it guides the visible light precision tracking module to search and track (precise tracking) the area near the angle information output in step S2. When the visible light precision tracking module tracks the target, it outputs high-precision angle information of the target (accuracy within the range of 20μm to 100μm) and sends it to the control unit (detection, tracking, and control module). If it determines that the laser anti-nuclear system does not have a killing capability against the target, it abandons the target, returns to step S2, and tracks the next target.

[0047] S4. After receiving the high-precision angle information from the visible light precision tracking module, the control unit (detection, tracking and control module) controls the laser ranging module to emit a laser beam to measure the target distance, and superimposes the high-precision angle information to form the target's high-precision azimuth, elevation and distance information.

[0048] S5. The control unit (laser control module) receives high-precision azimuth, elevation, and distance information of the target, controls the energy storage battery module to provide high-power power to each wind-cooled laser source, and selects the appropriate power of the laser beam emitted by the wind-cooled laser source according to the distance and type of the target, usually between 10% and 100%. Multiple wind-cooled laser sources emit beams to the beam spatial energy combining module, which combines the multiple laser beams into a higher-power laser beam.

[0049] S6. The control unit (laser control module) controls the beam orientation module to match the beam focusing distance according to the distance information of the attack target, and emits a high-energy laser beam sent by the beam spatial energy synthesis module at the same angle to damage the target according to the high-precision target angle information provided by the visible light tracking module.

[0050] S7. The control unit (laser control module) observes the damage effect on the target based on the target image information. When it is found that the damage effect of the laser on the target is not obvious, it can control the beam orientation module to deflect at a certain angle according to the target image information, so that the high-energy laser beam damages different positions of the target until the best damage effect is achieved.

[0051] S8. The control unit (detection, tracking and control module) provides the target's angle, distance and image information in real time. The control unit (damage judgment module) makes a judgment on whether the target is damaged based on the changes in the target's angle or distance and / or abnormalities in the target's image information. If the target is not damaged, laser damage continues. If the target is determined to be damaged, steps S2 to S8 are repeated to detect, track and damage the next target.

[0052] During the continuous damage to the target by the laser anti-nuclear system, it is necessary to pay attention to the operating temperature of each air-cooled laser source and the remaining emission time. Based on the remaining emission time and the target threat situation, the attack strategy should be adjusted in a timely manner, such as using a lower emission laser power and close-range laser damage to the target. When the remaining emission time is not enough for one attack, the laser damage attack should be stopped.

[0053] During system operation, the laser control module monitors the power level of the energy storage battery modules of each air-cooled laser source. If the power level of the energy storage battery module is lower than the threshold (70%), the power supply module is controlled to charge the energy storage battery module.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

6. The method of operating the portable laser anti-radiation system as described in any one of claims 1 to 5, characterized in that, Includes the following steps: S1. After powering on and completing timing and positioning, the control unit receives rough external information about the target from the external network and converts it into information about the angle, distance, speed, and type of the laser anti-radio system deployment location. S2. For a target to be destroyed, the control unit sends rough external information of the target to the infrared detection and tracking module and the visible light detection and tracking module. The infrared detection and tracking module and the visible light detection and tracking module search for and track the target. When either the infrared detection and tracking module or the visible light detection and tracking module searches for and tracks the target, the other module simultaneously searches for and tracks the target to confirm its position, and outputs the target's angle information based on the center point position of the tracked target, and sends it to the control unit. S3. The control unit determines whether the laser anti-nuclear system has the ability to kill the target based on the type of the target. If so, it guides the visible light precision tracking module to search and track the area near the angle information output in step S2. When the visible light precision tracking module tracks the target, it outputs the high-precision angle information of the target and sends it to the control unit. If it is determined that the laser anti-nuclear system is not capable of killing the target, then abandon the target and return to step S2 to track the next target; S4. After receiving the high-precision angle information sent by the visible light precision tracking module, the control unit controls the laser ranging module to measure the target distance and superimposes the high-precision angle information to form the target's high-precision azimuth, elevation, and distance information. S5. The control unit receives the high-precision azimuth, elevation, and distance information of the target, and selects an appropriate wind-cooled laser source to emit laser beam power according to the distance to the target and the target type. Multiple wind-cooled laser sources emit beams to the beam spatial energy combining module, and the beam spatial energy combining module combines multiple laser beams into a high-energy laser beam. S6. The control unit controls the beam orientation module to match the beam spot focusing distance according to the distance information of the attack target, and to emit the high-energy laser beam sent by the beam spatial energy synthesis module at the same angle to damage the target according to the high-precision target angle information provided by the visible light precision tracking module. S7. The control unit observes the damage effect on the target. If the damage effect of the laser on the target is not obvious, the control unit controls the beam orientation module to deflect the beam so that the high-energy laser beam damages different positions of the target. S8. The control unit determines whether the target is damaged. If the target is not damaged, laser destruction continues. If the target is determined to be damaged, repeat steps S2 to S8 to detect, track, and damage the next target.

7. The working method of the portable laser anti-nuclear system as described in claim 6, characterized in that: In step S1, if there are multiple targets, the threats are further prioritized based on the current situation of the protected targets to determine the order in which targets should be destroyed.
