Description

Technical Field

[0001] This invention belongs to the field of single-person portable optoelectronic countermeasures equipment technology, specifically involving a lightweight single-person intelligent laser system and its usage method. It is mainly used for rapid detection, identification and hard-kill destruction of targets such as low-altitude, slow-speed, small drones and floating objects in scenarios such as border patrol, key area defense and field air defense. Background Technology

[0002] Currently, laser systems used for counter-drone missions are primarily high-powered equipment deployed on vehicles, ships, or fixed sites. While these systems have high energy output, they are also bulky and heavy, typically requiring dedicated transport platforms and multi-person operating teams, making them unsuitable for single-person transport and mobile deployment. When dealing with sudden, dispersed small drone threats, these systems suffer from inherent drawbacks such as slow deployment, delayed response, and inability to accompany infantry squads on maneuvers, failing to meet the urgent needs of modern frontline troops for immediate and flexible accompanying air defense firepower.

[0003] The few existing laser weapons that attempt to be manned mostly adopt a design approach that highly integrates the laser, power supply, cooling, and control system into a single handheld device. This design results in an excessively heavy and bulky handheld device, making it difficult for soldiers to hold and aim stably for extended periods. Furthermore, the system has short battery life and poor environmental adaptability. Simultaneously, its functionality is limited, lacking effective automatic target search, identification, tracking, and intelligent fire control management capabilities. Operation is complex, requiring highly skilled personnel, and its effectiveness is limited in complex combat environments. Essentially, it does not resolve the fundamental contradiction between portable single-person use and high-efficiency combat.

[0004] In summary, existing laser systems face three main challenges in single-person applications: first, the conflict between system weight under high power requirements and individual portability; second, the conflict between limited energy supply and continuous combat needs; and third, the conflict between complex combat missions and easy single-person operation. Currently, there is a lack of a truly lightweight, portable, long-endurance, intelligent, and environmentally adaptable integrated laser system for single-person use to effectively enhance the infantry unit's ability to independently counter low-altitude UAV threats. Summary of the Invention

[0005] The purpose of this invention is to provide a lightweight, single-person intelligent laser system and its usage method, which solves the problems of excessive carrying load, insufficient continuous combat capability, low level of intelligence, and complex human-machine operation in existing single-person laser weapons.

[0006] The first objective of this invention is to provide a lightweight, single-person intelligent laser system, which adopts a modular and separate architecture, including a handheld main unit module, a laser module, and a battery module. The laser module and battery module are physically separate from the handheld main unit module, and are equipped with a carrying component for hanging on the user's waist, so that the weight of the laser module and battery module is supported by the user's waist; the handheld main unit module is designed for the user to hold and operate with both hands. The laser module contains a laser generation unit and a heat dissipation unit, which are used to generate and output the high-energy laser beam required to destroy the target. The battery module is a pluggable and replaceable structure used to provide operating power for the laser module and the handheld host module; The handheld host module has a highly integrated structure, and its housing integrates at least the following components: an imaging optical component, including a visible light imaging channel and an infrared thermal imaging channel, for day and night observation, search and imaging of targets; a beam control component, for controlling the direction of laser emission and keeping the imaging optical axis coaxial or parallel to the laser emission optical axis; a laser ranging component, for measuring distance information to the target; and a display control component, including a display screen and processing circuitry, for displaying images, system information and providing a human-machine interface. The laser module is connected to the handheld host module via optical fiber to transmit laser light; the battery module is connected to both the laser module and the handheld host module via power cables to provide power. The system also integrates: a target search and automatic tracking unit, used to automatically identify, capture and continuously track moving targets within the imaging field of view; a Beidou positioning and orientation unit, used to obtain the system's own geographical location and heading information; a status monitoring unit, used to monitor the system's battery power, component temperature and operating status in real time; and a data recording and playback unit, used to record video, images and operational data during combat and reproduce the strike process.

[0007] Furthermore, the system also includes an intelligent laser lighting unit; The intelligent laser illumination unit is integrated into the handheld host module, including a variable beam expander group and a continuous optical power adjustment module; The handheld host module automatically calculates the required illumination laser divergence angle and output power based on the target distance value obtained in real time by the laser ranging component and the ambient background brightness value detected by the imaging optics component. It then drives the variable beam expander group to adjust the beam divergence angle to match the target area size. At the same time, it controls the optical power continuous adjustment module to adjust the output power so that the illuminance value of the target area on the detector is maintained within the preset dynamic range.

[0008] Furthermore, the system also includes a handheld vibration compensation unit; The handheld vibration compensation unit includes a vibration sensing module and an optical axis adaptive compensation module; The vibration sensing module is installed inside the housing of the handheld main unit module and is used to collect multi-dimensional vibration signals generated by handheld operation in real time. The optical axis adaptive compensation module is connected to the vibration sensing module and the beam control component respectively. It is used to generate compensation control commands based on the real-time vibration signals collected by the vibration sensing module, and drive the precision actuator in the beam control component to make real-time fine adjustments to the laser emission optical path to compensate for the optical axis offset and defocus caused by vibration.

[0009] Furthermore, the system also integrates a multi-sensor fusion target recognition unit; The multi-sensor fusion target recognition unit is used to synchronously process and fuse target temperature distribution features from the thermal imaging component, target texture and contour features from the imaging optical component, and target distance change rate features from the laser ranging component, in order to comprehensively generate a motion feature map of the target; The multi-sensor fusion target recognition unit has a pre-stored typical target feature model. By comparing and analyzing the generated real-time target motion feature map with the preset bird flapping wing feature model and UAV rotor feature model, it can distinguish and identify bird and UAV targets, and trigger a target lock prompt when the target is identified as a UAV target.

[0010] The second objective of this invention is to provide a method of using the aforementioned portable, single-person intelligent laser system, comprising the following steps: S1 system carrying configuration: The user attaches the laser module and battery module to the waist via the carrying component, and holds the handheld main unit module, forming a carrying state in which the waist bears the main weight and the handheld main unit is used for operation; S2 Target Search and Fusion Display: The airspace is searched by the imaging optical components of the handheld host module to acquire target images, which are then displayed on the display control component; S3 Target Tracking, Locking and Ranging: After a target is detected, the target search and automatic tracking unit is activated to automatically track and lock onto the target, and the real-time distance information of the target is obtained through the laser ranging component; S4 Laser Damage Strike: After confirming that the target has been stably locked, the laser module is controlled to output a high-energy laser beam to damage the target; S5 Integrated Information Management and Status Monitoring: During combat operations, the system's power and temperature status are monitored in real time through the status monitoring unit, and its own location information is obtained through the Beidou positioning and orientation unit. Combined with the map positioning and situation display unit, the battlefield situation is generated.

[0011] The present invention has the following beneficial effects: (1) By designing the laser module and battery module independently and mounting them on the user's waist, the present invention transfers the main weight of traditional integrated heavy equipment to the hip, which has a stronger load-bearing capacity, while the handheld host module is highly integrated and significantly lightweight, solving the problem of excessive load and poor mobility of a single person carrying a heavy laser system, enabling a single person to accompany and carry it for a long time and deploy it quickly without affecting tactical actions.

[0012] (2) The multi-sensor fusion target recognition unit in this invention can effectively distinguish between drones and birds, reducing the false alarm rate; the intelligent laser illumination unit and the handheld vibration compensation unit respectively ensure clear imaging under any lighting conditions and high-precision aiming in dynamic environments; the adaptive damage control based on target characteristics realizes the optimal utilization of laser energy.

[0013] (3) The lens anti-fog unit and the quickly pluggable and replaceable battery module in this invention ensure that the system can work stably for a long time in harsh environments such as rain and fog. The complete internal status monitoring and alarm capabilities enhance the system's battlefield survivability. The integration of Beidou positioning and orientation and short message communication capabilities makes the system not only an independent strike node, but also an information terminal that can be located, commanded, and reported, seamlessly integrating into a wider range of combat systems.

[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0018] To fully understand this invention, detailed steps and structures will be presented in the following description to illustrate the technical solution of this invention. Preferred embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0019] Example 1

[0020] like Figures 1 to 4 In one embodiment of the lightweight single-person intelligent laser system of the present invention, the system includes a handheld main unit module 1, a laser module 2, and a battery module 3. The laser module 2 and battery module 3 are mounted on the waist of a single-person tactical belt or a dedicated vest via a standardized carrying interface integrated into the module housing. The carrying interface typically employs a combination of quick-release mechanical buckles and anti-slip webbing to ensure the module does not detach during strenuous tactical movements such as running and crawling, while also distributing most of the system's total weight through the hips, reducing upper limb load. The handheld main unit module 1 is ergonomically designed with a main grip and a foregrip, facilitating two-handed gripping, shoulder aiming, and precise operation. Its weight is controlled within a range that allows for stable holding by a single person for extended periods, thus achieving optimal ergonomic distribution between waist support and handheld operation.

[0021] Laser Module 2 is the functional unit that generates a high-energy destructive beam, internally containing a high-power fiber laser structure. Specifically, it includes: a pump source composed of an array of multiple semiconductor laser diodes to provide excitation light; a circuit control board providing precise current drive and pulse modulation for the pump source; a beam combiner that efficiently couples the pump light into the gain fiber; a section of special gain fiber serving as the core medium for laser generation; and a beam-shaping optical element group consisting of a collimating lens, a beam expander, and a focusing lens to shape the laser output from the fiber into a parallel beam or a beam with a specific divergence angle that meets far-field focusing requirements. To ensure thermal stability under high-power operation, Laser Module 2 integrates a highly efficient liquid cooling system. The system includes a miniature circulating pump, a microchannel cold plate closely attached to the pump source and fiber combiner, and aluminum heat sinks located on the module's sidewalls. The coolant circulates in a closed pipeline, conducting the heat generated by the core components to the heat sinks, thereby controlling the internal temperature of the laser within the allowable operating range and ensuring long-term stability of the output power and device lifespan.

[0022] The battery module 3 casing is constructed from high-strength engineering plastic and a metal frame, providing dustproof, waterproof, and impact-resistant capabilities. Internally, it consists of multiple high-rate, high-energy-density lithium-ion battery cells connected in series and parallel. The top panel of the battery module 3 integrates a quick-plug power interface with a foolproof design, mechanical locking, and sequential connector engagement function to prevent accidental insertion and arcing caused by live insertion. The panel also features a digital display or LED strip to show the remaining battery level. The battery module 3 provides independent, filtered, and regulated DC power to the laser module 2 and the handheld host module 1 via two quick-release, bend-resistant cables. The standard configuration includes at least one fully charged backup battery module 3 of the same model. When the primary battery's power falls below a preset threshold, the system issues an audible and visual alarm. The operator can complete the energy replacement within seconds by simply pressing the latch, removing the old battery, and inserting the new one.

[0023] The handheld host module 1 is the central hub for information processing, situational awareness, and human-computer interaction in the entire system. Internally, it employs a compact, multi-layered stacked architecture. Multiple optical windows are located at the front of the housing, each corresponding to a different optical channel. The imaging optics utilize a common-aperture beam splitting design. After passing through the main objective lens, the incident light is split into two paths by a beam splitter: one path enters the visible light channel, received by a high-resolution, high-frame-rate CMOS image sensor, used to acquire detailed color images during the day or under good lighting conditions; the other path enters the infrared thermal imaging channel, received by an uncooled vanadium oxide focal plane detector, used to detect the temperature difference between the target and the background, enabling observation under conditions such as nighttime, smoke, and fog. The video signals from both channels are sent to a dedicated image processing board, which runs a real-time image fusion algorithm to perform pixel-level fusion and enhancement of the detailed texture of the visible light image and the temperature contrast information of the thermal imaging image, outputting a more easily identifiable composite image.

[0024] The beam control component is a precision servo mechanism within the handheld main unit module 1. Its core is a high-precision, high-dynamic-response two-axis stabilized turntable. The turntable is connected to the optical head via a flexible coupling, enabling it to drive the optical head to perform a wide range of high-precision movements in azimuth and pitch. The turntable integrates a high-resolution encoder for real-time angular position feedback. Furthermore, a set of reflectors is placed in the optical path to precisely coaxially combine the destruction laser beam from the fiber optic interface with the observation optical path, ensuring that the aiming line is perfectly aligned with the laser emission line. The servo control system drives the turntable motor according to target tracking commands or manual control commands, achieving automatic tracking or precise manual aiming of the moving target.

[0025] Furthermore, the beam control assembly also includes a fast-reflecting mirror, which is mounted on the optical platform supported by the servo turntable and located in the laser transmission optical path output by the laser module. Specifically, the fast-reflecting mirror is a two-dimensional high-speed deflecting mirror driven by a piezoelectric ceramic driver or a voice coil motor, and its deflection response frequency is higher than the motion bandwidth of the servo turntable. During target tracking and engagement, the servo turntable and the fast-reflecting mirror constitute a composite axis control system and work together. The servo turntable, as the coarse tracking axis, is responsible for responding to the target's large-scale movement, driving the entire optical head to capture and initially stabilize the target at the center of the imaging field of view. The fast-reflecting mirror, as the fine tracking axis, receives the residual error signal from the image processor and performs rapid fine-tuning of the laser beam emission angle at the milliradian level and above at hundreds of hertz to compensate for the tracking residual of the servo turntable in real time, eliminate the influence of high-frequency micro-vibrations of the carrier on the aiming line, and ultimately precisely lock the laser spot onto the predetermined impact point of the target, thereby achieving high-precision damage.

[0026] The laser ranging component is coaxially integrated with the observation optical path. It uses an eye-safe laser as its light source, emitting narrow pulse laser light at a high repetition rate towards the target and receiving extremely weak reflected echoes. By accurately measuring the time difference between transmission and reception, it calculates and outputs the real-time distance to the target, achieving a ranging accuracy of ±1 meter and a refresh rate of over 10 Hz.

[0027] The display and control unit is the primary human-machine interface. It includes a high-brightness, high-contrast miniature active-matrix organic light-emitting diode (EMD) display screen located behind the eyepiece, providing the operator with a view. The screen overlays rich graphical information, including the electronic compass, pitch angle, target frame, distance reading, battery status, and system menus. The processing core employs a high-performance, low-power embedded system, running control software based on a real-time operating system. This software is responsible for coordinating all sensor data, executing image processing algorithms, managing user input, and controlling various actuators.

[0028] Laser module 2 is connected to handheld host module 1 via a low-loss quartz optical fiber with an armored protective layer. Both ends of the fiber are precision, adjustment-free fiber optic connectors, ensuring high efficiency and high directional stability of laser transmission. Battery module 3 is connected to the other two modules via a waterproof power connector and cable with a locking mechanism for power transmission.

[0029] The target search and automatic tracking unit utilizes background modeling, motion detection, and correlation filtering algorithms to automatically detect and identify potential threat targets in image sequences, outputting the target's pixel coordinates in the image. These coordinates are then converted into angular displacement commands for the servo turntable, achieving closed-loop automatic tracking. The BeiDou positioning and orientation unit includes a BeiDou satellite navigation receiver and a magnetoresistive digital compass, providing real-time system latitude, longitude, altitude, and true north heading angle, providing fundamental data for autonomous navigation and situation map generation. The status monitoring unit reads data from the temperature, voltage, and current sensors of each module to monitor the system's health status in real time, and issues multi-level alarms through graphics, sound, and other methods when parameters exceed limits. The data recording and playback unit controls a large-capacity solid-state storage device to synchronously record multiple video streams, all sensor data, control commands, and event logs throughout the entire mission cycle with timestamps, supporting detailed post-mission analysis and evaluation.

[0030] In one specific embodiment, to optimize the damage effect on the target and energy utilization efficiency, the system also integrates a laser damage control unit. The laser damage control unit is a software function module running within the main control processor of the handheld host module 1. When the operator prepares to fire, the laser damage control unit automatically reads the real-time target distance value output by the laser rangefinder and, based on a preset distance-energy mapping model or atmospheric transmission model, automatically calculates the optimal laser output power, pulse width, and emission duration required to achieve the damage effect. The laser damage control unit provides recommended parameters on the display interface, allowing the operator to choose to confirm automatic settings or manually fine-tune them, thereby maximizing system energy conservation while ensuring damage effectiveness.

[0031] In one specific embodiment, the processor of the handheld host module 1 also runs a map mapping and situation display unit. Based on the real-time latitude and longitude coordinates and heading angle obtained by the BeiDou positioning and orientation unit, the map mapping and situation display unit calls digital map data pre-stored in the memory to generate an electronic map display on a designated area of ​​the screen of the display control component. The map mapping and situation display unit can mark the local location on the map in the form of icons, and simultaneously calculate the estimated geographical location of the tracked target based on the distance and orientation information of the tracked target, dynamically drawing its movement trajectory on the map, providing a single person with intuitive local battlefield situational awareness.

[0032] In one specific embodiment, to meet the command and communication needs in remote environments without public networks, the system also integrates a remote management unit. The core of the remote management unit is a BeiDou short message communication module integrated within the handheld host module 1. Key status information collected by the status monitoring unit, such as system battery level, temperature, and location coordinates, can be reported to the rear command center periodically or on demand via encrypted short messages through the remote management unit. Simultaneously, the remote management unit can also receive text commands from the command center, such as target priority changes and retreat instructions, and display them on the operator's screen, thereby achieving remote command and management beyond visual range.

[0033] In one specific embodiment, the system also integrates a system calibration unit. The system calibration unit is a functional procedure used for pre-shipment or pre-mission maintenance. In calibration mode, the operator aligns the system with a cooperative target at a known distance, and the system uses image processing algorithms to analyze the center deviation between the laser spot and the reticle in the imaging optics. The system calibration unit automatically corrects the optical path deviation by issuing fine-tuning commands to the fast-reflecting mirror or focusing mechanism in the beam control assembly, ensuring that the laser emission axis and the imaging observation axis remain highly coaxial with high precision throughout the full zoom range.

[0034] In one specific embodiment, to improve the usability of the optical windows in harsh environments such as rain, fog, and high humidity, the system also integrates a lens anti-fog unit. The lens anti-fog unit includes a transparent electrically heated film (e.g., an indium tin oxide film) attached to the inner or outer side of each optical window lens at the front end of the handheld host module 1, and a temperature control circuit. The electrically heated film can be an indium tin oxide film. When the status monitoring unit detects that the ambient humidity exceeds a threshold or the temperature is close to the dew point, the temperature control circuit automatically provides a low-voltage current to the electrically heated film, making the lens surface temperature slightly higher than the ambient temperature, thereby effectively preventing water vapor condensation and ensuring clear imaging.

[0035] In one specific embodiment, to meet the safety management requirements of equipment used in specific areas, the system also integrates an electronic fence unit. The electronic fence unit is a software function running within the handheld host module 1. The operator or commander can pre-set a polygonal geographical boundary composed of multiple BeiDou coordinate points via a host computer and load it into the system memory. During operations, the electronic fence unit continuously compares the real-time position obtained by the BeiDou positioning and orientation unit with the preset boundary. Once the system position exceeds the set boundary, the display control component will immediately display a boundary violation warning message and issue an audible alert, reminding the operator to return to the authorized operational area, thereby achieving control over the usage range of high-value equipment.

[0036] In one specific embodiment, to optimize observation performance under nighttime and low-light conditions, the system integrates an intelligent laser illumination unit. This intelligent laser illumination unit is integrated into the optomechanical structure of the handheld host module 1, and its hardware includes: a Galilean variable beam expander group driven by a stepper motor that continuously adjusts the beam divergence angle by changing the lens spacing; and a continuous optical power adjustment module based on a digital-to-analog converter and a precision constant current source circuit.

[0037] When the operator activates or the system automatically enters low-light mode, the main control processor continuously reads two key parameters: the real-time target distance value D from the laser ranging component, and the average grayscale value L, which reflects the ambient background brightness, output from the visible light CMOS sensor automatic exposure control circuit.

[0038] The processor's built-in optimization algorithm calculates two core control variables in real time based on a pre-calibrated model: the beam divergence angle θ and the initial estimate P of the illumination laser power.

[0039] The calculation of the beam divergence angle θ aims to achieve the desired coverage area of ​​the target region. In this embodiment, the divergence angle θ is inversely proportional to the target distance D, meaning the divergence angle decreases with increasing distance, thus keeping the coverage size of the illumination spot at the target distance essentially constant. As an exemplary implementation, the processor can use the following formula... The divergence angle is calculated, where W is a coverage constant preset according to the system's field of view and observation requirements. Based on this, the processor sends pulse commands to the stepper motor driver of the variable beam expander group, driving the mirror group to move to the position corresponding to θ.

[0040] The initial estimation of the illumination laser power P aims to compensate for geometric and atmospheric attenuation caused by increasing distance, and to ensure that the target reflected light achieves the expected response grayscale on the CMOS sensor. The processor calculates the initial power value based on a pre-calibrated model that at least characterizes the physical relationship between power P and the square of the distance D, and a negative correlation with the ambient background brightness L. As a non-limiting example, the processor can calculate the power reference value using the following formula: Where K is a comprehensive calibration coefficient related to the optical system's transmission efficiency, target reflection characteristics, and sensor responsivity.

[0041] Subsequently, the processor sets the reference voltage of the optical power continuous adjustment module through a digital-to-analog converter to finely control the drive current of the illumination laser diode, thereby stabilizing the output optical power near the P value.

[0042] After the illumination is turned on, the system continuously monitors the imaging quality indicators of the target area in the image, such as the average grayscale value or contrast of the target area. The processor compares the monitored value with the preset optimal dynamic range center value and runs a closed-loop adjustment algorithm to fine-tune the laser power in real time, ultimately stabilizing the illuminance of the target area on the imaging sensor within the preset response range, thus achieving adaptive optimal illumination.

[0043] In one specific embodiment, to overcome the impact of unavoidable physiological tremors and environmental disturbances during handheld operation on high-precision laser aiming, the system incorporates a handheld vibration compensation unit. This unit consists of three parts: sensing, calculation, and execution. The vibration sensing module is a miniature, high-precision inertial measurement unit (IMU) patch-mounted on the main optical platform inside the handheld host module 1. It incorporates a three-axis gyroscope and a three-axis accelerometer, capable of sampling and outputting minute perturbation signals of the carrier's instantaneous optical axis in the angular velocity and linear acceleration dimensions at frequencies exceeding one kilohertz. The optical axis adaptive compensation module is a real-time control algorithm running on a dedicated digital signal processor. It performs high-speed filtering, noise reduction, and computation on the raw vibration signals collected by the IMU, accurately estimating the main vibration components causing aiming line deviation and focus drift within milliseconds. Subsequently, the algorithm generates digital compensation commands with equal amplitude but opposite phase. Digital compensation commands are converted into analog driving voltages, which are applied to two key actuators within the beam control assembly: one is a high-speed voice coil motor-driven fast-reflecting mirror that controls the beam direction, causing it to undergo a micro-arc-level reverse deflection to directly correct the optical path direction; the other is a piezoelectric motor-driven focusing lens that controls the focusing, causing it to undergo a micrometer-level axial displacement to compensate for defocusing caused by vibration. This high-speed closed-loop control effectively isolates hand-held jitter below 20 Hz, ensuring that the laser beam's spot position fluctuation at the target is far less than the spot size required for damage, thus guaranteeing a high first-shot hit probability in dynamic environments.

[0044] In one specific embodiment, to improve the accuracy of aerial target identification and reduce the risk of misjudgment and accidental shooting of non-threat targets such as birds, a multi-sensor fusion target identification unit runs within the processor of the handheld host module 1. The multi-sensor fusion target identification unit implements a multi-feature-level fusion identification process. At the feature extraction layer, the multi-sensor fusion target identification unit processes three data streams in parallel: for the thermal imaging video stream, it extracts the temperature statistical features of the moving target area, such as the highest temperature point, average temperature, and temperature distribution uniformity, paying particular attention to the presence of local high-temperature points consistent with the motor's heating characteristics; for the visible light video stream, it extracts the target's shape features, such as contour moments, aspect ratio, and texture features; for the high-speed ranging data stream from the laser rangefinder, it analyzes its time-varying patterns using short-time Fourier transform to extract the periodic micro-Doppler feature spectrum caused by the target's rotor or flapping wing motion. At the feature fusion and decision layer, the multi-sensor fusion target identification unit uses a weighted or deep learning model-based method to align and fuse the heterogeneous features obtained from different physical principles over time, forming a high-dimensional comprehensive target feature vector. The multi-sensor fusion target recognition unit internally stores a classification model database trained with a large amount of real-world data, including flapping wing models of various typical birds and rotor vibration models of various UAV models. During recognition, the multi-sensor fusion target recognition unit calculates the matching degree between the current target's comprehensive feature vector and the features of various models in the database. If the main peak frequency and harmonic components of its micro-Doppler spectrum highly match a certain type of bird model, and its thermal characteristics show a uniform biological thermal distribution, it is identified as a bird, and a green bird icon is displayed on the screen. If its micro-motion spectrum matches a certain type of UAV model, and strong local hotspot features corresponding to the motor position are detected simultaneously, the system determines it as a UAV threat with high confidence, automatically marks a red threat box on the screen and issues a warning sound, and prioritizes the automatic tracking and locking process, improving the ability to distinguish between small UAVs and birds, especially at long distances, in complex backgrounds.

[0045] Example 2

[0046] This embodiment provides a method for using the portable, single-person intelligent laser system based on Embodiment 1 above, such as... Figure 5 As shown, it includes the following steps: S1 System Pre-Battle Check and Carry-on Configuration: The operator first prepares for the mission. They then sequentially inspect the laser module 2, battery module 3, and handheld main unit module 1 for any damage to their appearance and cleanliness of the connection interfaces. Powering on the system, they check the system's self-test process for normal operation and confirm that the status monitoring unit has no fault alarms. The operator checks the battery level of the backup battery module 3. After confirming it is normal, they power off the system. The laser module 2 and main battery module 3 are securely attached to the left and right sides of the tactical belt via their quick-release connectors at the bottom, adjusting the webbing length to ensure even weight distribution and not hindering tactical movements. The operator removes the fiber optic patch cord from the laser module 2, aligns its precision connector with the fiber optic adapter interface on the back of the handheld main unit module 1, and inserts it smoothly until a clear locking sound is heard. One end of each power cord is reliably connected to the power input ports of the handheld main unit module 1 and laser module 2, and the other end is connected to the corresponding output socket of the battery module 3. The operator holds the handles with both hands and raises the system to the combat-ready position.

[0047] S2 System Power-On Initialization and Battlefield Environment Scan: The operator presses the power switch on handheld main unit module 1, and the system begins a power-on self-test. During the self-test, the display shows the connection status of each module, sensor status, BeiDou positioning status, and battery level in sequence. After the self-test passes, the system automatically enters the main observation interface. The operator first selects the observation mode suitable for the current weather conditions using the function keys: visible light or fusion mode during the day, and thermal imaging or fusion mode at night. The operator observes the surrounding environment through the display and can also view their own BeiDou positioning position displayed on the electronic map in the corner of the screen. By rotating their body and manually adjusting, the operator performs a fan-shaped or circular search of the key airspace designated for the mission, utilizing the high resolution and wide field of view of the imaging optical components to detect suspicious targets as early as possible.

[0048] S3 target detection, precise identification, and stable tracking: When a suspicious moving point-like target is detected on the screen, the operator uses the joystick to hover the aiming cursor over the target and half-presses the track button. At this point, the target search and automatic tracking unit activates, and the servo system automatically drives the optical system to initially stabilize the target in the center of the field of view. The laser rangefinder begins working, displaying the real-time distance next to the target on the screen. Simultaneously, the multi-sensor fusion target recognition unit starts in the background, performing rapid feature analysis on the currently locked target. The system displays an icon of the recognition result next to the target, such as the outline of a bird or a simplified diagram of a drone, possibly accompanied by text labels. If the target is identified as a drone, the operator fully presses the track button, and the system enters stable tracking mode. The servo system then locks the target firmly in the center of the field of view with higher bandwidth and accuracy, regardless of the target's movement. The ranging information is continuously updated. The operator can observe the target's distance, speed, and orientation information displayed on the screen at any time.

[0049] S4 Aiming Correction, Decision Making, and Laser Strike: After the target is stably tracked, the operator enters the firing preparation phase. During this time, the handheld vibration compensation unit remains active to ensure a stable aiming line. In low-light conditions, the intelligent laser illumination unit adaptively activates based on the environment, optimizing image quality. The operator can fine-tune the aiming point using a joystick, selecting to strike specific parts of the target, such as the rotor or center of a drone. When deciding to fire, the operator moves their thumb to the red laser firing button. First, the laser pre-activation button is pressed, and the system performs a final self-check. The energy storage capacitor in laser module 2 begins charging, and a clear laser-ready indicator appears on the screen. After confirming everything is correct, the operator decisively presses the firing button. The main control processor instantly calculates the required laser power, pulse width, and irradiation time based on the real-time target distance, current atmospheric parameters, and the selected damage mode, and sends a trigger signal to laser module 2. The pump source within laser module 2 is driven by a high-power current, generating a high-power laser. This laser is transmitted via fiber optic cable and, through the precisely aligned beam combining path within the handheld main unit module 1, is fired at the target along a path perfectly aligned with the aiming line. Operators observe the effects of the strike on the screen, such as the target tumbling out of control, emitting smoke, or falling.

[0050] S5 Mission Integrated Information Management and Post-Military Response: Throughout the mission, the following processes continued in the background: The status monitoring unit continuously refreshed and evaluated thousands of data points in real time, including battery voltage, laser core temperature, and operating current of each circuit board. Any abnormal parameters triggered tiered alarms. The BeiDou positioning and orientation unit continuously output the precise position, altitude, and heading of the aircraft. The map positioning and situation display unit plotted this aircraft position information, along with the track points of tracked or attacked targets, in real time on the electronic map window of the display screen, forming a local battlefield situation map. The data recording and playback unit synchronously recorded observation videos, overlaid graphic information, all operation command logs, system status data streams, and audio, forming an unalterable and complete mission log file. After a strike, the operator continuously observed the situation to determine if the threat had been eliminated. If the battery power was low, a rapid replacement was performed. After the mission, the operator could disable the laser emission function but kept the system in a state of alert and observation. Upon returning to base, the recorded data could be exported via a wired data port for detailed post-battle debriefing, battle results evaluation, and training analysis. Throughout the process, if in an area without public mobile communication network coverage, the operator or commander can use the BeiDou short message communication module integrated into the system to send and receive encrypted status reports and brief instructions in the form of short messages, thereby achieving remote silent management beyond line of sight.
