Description

Technical Field

[0001] This invention relates to a low-observable active-passive combined blinding system for urban combat environments, belonging to the field of electronic countermeasures technology. Background Technology

[0002] With the development of modern military technology, various advanced optoelectronic sensors have been widely used in urban warfare environments. These sensors include, but are not limited to: white light and thermal imaging sights used by snipers, low-light night vision devices mounted on individual soldiers or vehicles, optoelectronic reconnaissance pods carried by drones, and infrared or laser guidance heads for precision-guided weapons (such as anti-tank missiles). These devices have greatly enhanced the enemy's situational awareness, target acquisition, and precision strike capabilities in complex urban terrain, posing a serious threat to our personnel and equipment.

[0003] To counter these threats, active optoelectronic countermeasures are typically employed to achieve active blinding, while passive optoelectronic countermeasures achieve passive covert jamming. While this can meet normal operational needs, single-mode countermeasures are poorly adaptable and risky in complex urban environments. For example, a purely laser-based countermeasure system is exposed the moment it is activated. Existing active-passive composite systems, such as laser-infrared active-passive composite guidance systems or active-passive composite imaging technologies, are designed for detection and imaging, not blinding. Therefore, there is a lack of a countermeasure system that can effectively combine active precision blinding and passive covert jamming while possessing high survivability. Based on this, this invention provides a low-observable active-passive composite blinding system for urban combat environments. Summary of the Invention

[0004] The technical problem that this invention aims to solve is the lack of an anti-counterfeiting system that can effectively combine active precision blinding and passive covert interference while possessing a high degree of survivability.

[0005] This invention provides a low-observable active-passive combined blinding system for urban combat environments. The proposed technical solution includes:

[0006] Active blinding module, used to fire a directed energy beam to saturate, interfere with or permanently damage enemy optical, infrared or laser sensors;

[0007] Passive blinding modules are used to deceive, interfere with, or disable enemy sensors or their detection algorithms by altering the thermal radiation or optical characteristics of a target area without actively emitting electromagnetic energy.

[0008] The low-observable platform is used to carry active and passive blinding modules to reduce its radar, infrared and visible light signature signals through shape, surface materials and thermal management technology.

[0009] The collaborative control unit is connected to the active blinding module, the passive blinding module, and the threat perception sensor integrated on the low observability platform. It is used to identify the type and location of the enemy sensor based on the data from the threat perception sensor, and autonomously select or collaboratively drive the active blinding module and the passive blinding module to execute the optimal blinding strategy according to the preset engagement rules.

[0010] Furthermore, the active blinding module includes a multi-band laser emission subsystem, capable of emitting adjustable power laser beams in one or more bands to interfere with enemy optical observation equipment.

[0011] Furthermore, the laser beam emitted by the multi-band laser emission subsystem has a programmable modulation method, including continuous wave, high repetition rate pulse, and coded pulse sequence, to achieve a multi-level blinding effect ranging from temporary glare interference to permanent hardware damage, targeting different sensor signal processing mechanisms.

[0012] Furthermore, the passive blinding module includes multiple projectable low-emissivity thermal decoys and a projection device for projecting the thermal decoys, wherein the thermal decoys are made of materials with extremely low infrared emissivity.

[0013] Furthermore, the collaborative control unit controls the projection device to deploy thermal decoys to the target area to create cold spots in the field of view of the enemy's thermal imaging sensor that are significantly different from the ambient background temperature, thereby disrupting image uniformity and interfering with the automatic target recognition algorithm.

[0014] Furthermore, the low observability platform has a multi-faceted, tilted design to scatter radar waves in a non-threatening direction; the surface of the low observability platform is covered with radar-absorbing material and a low infrared emissivity coating.

[0015] Furthermore, the low detectability platform also includes an active thermal management system, which includes built-in cooling pipes and heat dissipation devices to transfer and suppress the heat generated by the active blinding module and the passive blinding module.

[0016] Furthermore, the collaborative control unit includes an infrared focal plane array alarm covering 360 degrees and a laser alarm receiver, which are used to detect and locate the position and operating status of enemy sensors without actively emitting any detection signals.

[0017] The beneficial effects of this invention are:

[0018] This invention integrates active blinding, passive blinding, and low-detectability technologies in an unprecedented depth and coordinates them under a unified intelligent collaborative control unit. This minimizes the risk of being detected and countered by the enemy. It fully considers the characteristics of urban warfare, such as short line of sight, complex background, and diverse threat sources. It can effectively combine active precision blinding and passive covert interference, and at the same time has the advantages of high survivability, high countermeasure effectiveness, and high tactical flexibility. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of a low-observable active-passive combined blinding system for urban combat environments according to the present invention. Detailed Implementation

[0020] The preferred embodiments of the present invention will now be described in detail.

[0021] This invention provides a low-observable active-passive combined blinding system for urban combat environments, comprising: an active blinding module for emitting a directional energy beam to saturate, interfere with, or permanently damage enemy optical, infrared, or laser sensors; the active blinding module includes a multi-band laser emission subsystem capable of emitting adjustable-power laser beams in one or more bands to interfere with enemy optical observation equipment; the laser beams emitted by the multi-band laser emission subsystem have programmable modulation methods, including but not limited to continuous wave, high-repetition-rate pulse, and coded pulse sequences, to achieve multi-level blinding effects ranging from temporary dazzling interference to permanent hardware damage, targeting different sensor signal processing mechanisms; specifically, the visible to near-infrared band (0.4-1.1 micrometers) is used to counter human eyes, low-light night vision devices, and visible light cameras; the mid-infrared band (3-5 micrometers) is used to counter mid-infrared guidance and reconnaissance equipment; and the long-wave infrared band (8-12 micrometers) is used to counter long-wave infrared guidance and reconnaissance equipment.

[0022] A passive blinding module is used to deceive, interfere with, or disable the detection algorithms of enemy sensors (especially infrared thermal imaging sensors) by altering the thermal radiation or optical characteristics of the target area without actively emitting electromagnetic energy. The passive blinding module includes multiple projectable low-emissivity thermal decoys and a projection device for projecting the decoys. The decoys are made of materials with extremely low infrared emissivity. A control unit controls the projection device to deploy the thermal decoys to the target area to create cold spots in the field of view of the enemy thermal imaging sensor that are significantly different from the ambient background temperature. This disrupts image uniformity and interferes with automatic target recognition algorithms. Specifically, after deployment, due to their extremely low infrared emissivity, the heat radiated by the thermal decoys is far lower than that of surrounding objects. In the field of view of the enemy thermal imager, these thermal decoys appear as extremely cold black dots that are out of place with the background. This abrupt and unnatural signal severely interferes with the automatic gain control (AGC) of the thermal imaging system and causes significant problems for image recognition and tracking algorithms, preventing them from effectively identifying real targets, thus achieving passive blinding.

[0023] The low-observable platform is used to carry active and passive blinding modules to reduce its radar, infrared, and visible light signatures through its shape, surface materials, and thermal management technology. The low-observable platform adopts a multi-faceted tilted design to scatter radar waves in a non-threatening direction. The surface of the low-observable platform is covered with radar absorbing material (RAM) and a low infrared emissivity coating. The low-observable platform also includes an active thermal management system, which includes built-in cooling pipes and heat dissipation devices to transfer and suppress the heat generated by the active and passive blinding modules, so as to avoid the formation of detectable infrared hotspots on the surface of the low-observable platform.

[0024] The collaborative control unit, connected to the active blinding module, the passive blinding module, and the threat perception sensor integrated on the low observability platform, is used to identify the type and location of enemy sensors based on the data from the threat perception sensor, and autonomously select or collaboratively drive the active blinding module and the passive blinding module to execute the optimal blinding strategy according to preset engagement rules. The collaborative control unit includes an infrared focal plane array alarm covering 360 degrees and a laser alarm receiver, which are used to detect and locate the position and operating status of enemy sensors without actively emitting any detection signals.

[0025] The blinding strategies executed by the collaborative control unit include:

[0026] Passive Priority Mode: When a threat is detected, it is determined to be a low threat that requires covert handling. The passive blinding module is used first to interfere with the threat and maintain the covertness of the position to the maximum extent. For example, several heat decoys are launched in the direction of the threat for covert interference.

[0027] Active precision strike mode: For high-threat or specific types of targets, if they are determined to be high-threat and need to be destroyed immediately, the active blinding module is used directly to blind them with high precision and high intensity.

[0028] Active-passive combined mode: If neither of the above two is fully applicable, active and passive blinding modules can be activated simultaneously or in a specific sequence. For example, the passive blinding module can be used to create a large-scale background clutter to force the enemy sensor to expose more features, while the active blinding module can be used to precisely suppress the key targets identified in it, and perform pinpoint elimination.

[0029] In summary, this invention achieves an unprecedented level of integration of active blinding, passive blinding, and low-observability technologies, all uniformly coordinated by an intelligent collaborative control unit. It comprehensively utilizes shape stealth, material stealth, and thermal management technologies, resulting in an extremely low probability of detection in standby and passive operating modes. The passive-first engagement principle further enhances its battlefield survivability. The combination of active and passive methods allows it to address a broader spectrum of threats, and their synergistic effect can produce a 1+1>2 effect. This results in high survivability, high counter-attack effectiveness, and high tactical flexibility, minimizing the risk of detection and countermeasures by the enemy. It fully considers the characteristics of urban warfare—short line-of-sight, complex backgrounds, and diverse threat sources—effectively combining active precision blinding and passive concealment interference. Its rapid response and precision strike capabilities are particularly suitable for close-range, high-intensity urban combat environments.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
