Technical Field
[0001] This application relates to the field of smart munitions protection technology, and in particular, to a smart blockade unit anti-countermeasure system. Background Technology
[0002] With the rapid development of anti-blockade technology, enemy mine-clearing equipment (such as electromagnetic mine-clearing vehicles and vibratory mine-clearing devices) and electromagnetic interference equipment have become the main threats to smart blockade units. Existing smart blockade units lack targeted countermeasure designs.

They cannot meet actual needs. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, this application provides an intelligent blocking unit anti-countermeasure system to solve problems such as the reliance on manual operation for authorization, the single dimension of security judgment, the lack of dynamic permission management, the ease of log tampering, and the lack of re-authorization mechanism after firmware upgrades in existing remote control authorization mechanisms.

The infrared stealth layer is made of antimony-doped tin oxide / acrylic resin composite material and phase change material; The visual camouflage layer uses matte pigments that match the deployment area of the smart blockade unit, with a color deviation ≤ΔE76 3.0.

[0008] As an optional implementation of this application, the thickness of the radar absorbing layer is 0.1-3 mm; The thickness of the infrared stealth layer is 0.5-2mm; The thickness of the visual camouflage layer is 0.1-1 mm.

When the signal detection sensor detects a mine-sweeping device signal, the power management chip cuts off the power supply to the sensor and the triggering system, and the safety lock locks the warhead, causing the unit to enter a passive hibernation state and disguise itself as a non-threatening object. When the mine-sweeping device moves away, the power supply and standby state are automatically restored.

[0013] As an optional implementation of this application, the deception unit of the false target deception module also has a built-in battery.
[0014] As an optional implementation of this application, it also includes: an anti-interference communication module; The anti-interference communication module includes a frequency hopping communication unit and a signal encryption unit; The frequency hopping communication unit has a frequency hopping bandwidth of 10-20MHz and a frequency hopping rate of 50-100 hops / second, and can randomly hop within the 300MHz-3GHz frequency band to avoid electromagnetic interference.

When the signal detection sensor detects a mine-sweeping device signal, the power management chip cuts off the power supply to the sensor and the triggering system, and the safety lock locks the warhead, causing the unit to enter a passive hibernation state and disguise itself as a non-threatening object. When the mine-sweeping device moves away, the power supply and standby state are automatically restored.
[0027] Furthermore, the mine-clearing avoidance module also includes a signal recognition unit with a built-in mine-clearing equipment signal feature library, which is used to avoid misjudgment by comparing the detection signal with the feature library.

The signal encryption unit uses an encryption algorithm to encrypt the transmitted instructions and data to prevent the signal from being intercepted and cracked.
[0031] To more clearly illustrate the solution proposed in this application, a specific implementation method is provided below: The intelligent blockade unit anti-countermeasure system includes a multi-dimensional stealth protection module, a mine-clearing and avoidance module, a false target deception module, and an anti-interference communication module. Each module is connected by wires or wireless links and integrated inside or outside the intelligent blockade unit. The multi-dimensional stealth protection module includes a three-band composite camouflage coating and a low-detectability structure; The three-band composite camouflage coating consists of a radar absorbing layer, an infrared stealth layer, and a visual camouflage layer from the inside out, with thicknesses of 0.1-3mm, 0.5-2mm, and 0.1-1mm respectively. It is applied to the outer shell of the blockade unit through a spraying process. The radar absorbing layer can be made of ferrite or carbonyl iron powder / epoxy resin composite materials, carbon nanomaterials, silicon carbide, silicon nitride, carbon fiber, etc. The infrared stealth layer can be made of antimony-doped tin oxide (ATO) / acrylic resin composite material, phase change material, etc. The visual camouflage layer uses matte pigments that match the deployment area (such as soil, grass, gravel, rocks, etc.), with a color deviation ≤ΔE76 3.0; The low-detectability structure employs a streamlined or angled shell design to reduce the radar wave scattering angle.
[0032] The mine-sweeping avoidance module includes a mine-sweeping signal detection sensor and a passive sleep unit; The mine-clearing signal detection sensor includes an electromagnetic sensor and a vibration sensor; The electromagnetic sensor is used to detect the electromagnetic detection signal (frequency 10-100kHz) of the mine-clearing vehicle, with a detection distance ≤30m; The vibration sensor is used to detect the vibration signal of the mine sweeper (frequency 1-5Hz), with a detection distance ≤50m; The passive hibernation unit includes a power management chip and a safety lock. When the mine-sweeping signal detection sensor detects a signal from the mine-sweeping device, the power management chip cuts off the power supply to the sensor and the triggering system, and the safety lock locks the warhead, causing the unit to enter a passive hibernation state and disguise itself as a non-threatening object. When the mine-sweeping device moves away (e.g., the signal disappears for ≥30 seconds), the power supply and standby state are automatically restored. The deceptive target module includes a deception unit and a signal simulation unit; The decoy unit is an independent structure, with a ratio of 1:5 to 1:20 to the attack unit, and its shape is consistent with the attack unit. The signal simulation unit includes an electromagnetic signal generator and a trigger signal simulator, which can simulate the electromagnetic characteristics (frequency 50-500MHz, power 0.1-0.5W) and trigger signal waveform (pulse width 10-50μs, amplitude 3.3-5V) of the attack unit; when the system detects a countermeasure signal (such as an electromagnetic interference signal or a mine-sweeping signal), the decoy unit's signal simulation unit actively emits a false signal to attract the attention of the mine-sweeping equipment; The anti-interference communication module employs a frequency hopping communication unit and a signal encryption unit; The frequency hopping communication unit has a frequency hopping bandwidth of 10-20MHz and a frequency hopping rate of 50-100 hops / second, and can randomly hop within the 300MHz-3GHz frequency band to avoid electromagnetic interference. The signal encryption unit uses an encryption algorithm to encrypt the transmitted instructions and data to prevent the signal from being intercepted and cracked.
[0033] Furthermore, the three-band composite camouflage coating also contains an ultraviolet absorber (0.1%-15% by mass), which can absorb ultraviolet light with a wavelength of 200-400nm to evade ultraviolet detection equipment.
[0034] Furthermore, the mine-clearing avoidance module also includes a signal recognition unit with a built-in mine-clearing equipment signal feature library (storing the electromagnetic and vibration characteristics of mainstream mine-clearing equipment). By comparing the detection signal with the feature library, misjudgment is avoided (misjudgment rate ≤ 0.5%).
[0035] Furthermore, the deception unit of the false target deception module also has a built-in battery (capacity ≥5000mAh), which can continuously emit false signals for ≥24 hours.
[0036] For example, the multi-dimensional stealth protection module has a radar absorbing layer thickness of 2mm (carbonyl iron powder content of 60%), with a reflectivity of -18dB for 10GHz radar waves; an infrared stealth layer thickness of 0.8mm (ATO content of 30%), with an emissivity of 0.25; a visual camouflage layer thickness of 0.2mm, using desert yellow matte pigment, with a color deviation ΔE76 2.5; and a streamlined low-detectability structure, reducing the scattering cross-section by 65% compared to traditional square shells. The mine-clearing avoidance module's electromagnetic sensor has a detection frequency of 10-100kHz, and the vibration sensor has a detection frequency of 1-5Hz. When a 50kHz electromagnetic signal from a certain type of electromagnetic mine-clearing vehicle is detected (at a distance of 8m), the power management chip cuts off the power supply, and the unit enters a sleep state; 40 seconds after the mine-clearing vehicle moves away, it automatically resumes the ready-to-go state. The decoy unit to attack unit ratio of the decoy module is 1:10. The signal simulation unit simulates the 200MHz electromagnetic signal (0.3W power) and 30μs pulse trigger signal of the attack unit. When electromagnetic interference is detected, the decoy unit continuously emits false signals to attract mine-clearing equipment. The anti-interference communication module has a frequency hopping bandwidth of 15MHz, a frequency hopping rate of 80 hops / second, and uses AES-256 encryption. Under electromagnetic interference environment (interference power 10W), the communication interruption time is ≤5s / hour, and the normal response rate of the trigger signal is ≥90%. This system is integrated into the ground-attached blockade unit. Under mine-clearing and electromagnetic interference environments, the unit survival rate is 88%, effectively achieving long-term blockade.
[0037] This application's solution utilizes a multi-dimensional stealth protection module to reduce the identification rate of the blockade unit under radar, infrared, and visual detection to below 10%, and to reduce the mine clearance rate from the current 70% to 15%. The mine clearance avoidance module and the decoy module work together to further improve the unit's survival rate, increasing it from the current 30% to 85% in a mine-clearing environment. The anti-interference communication module employs frequency hopping and encryption technology to improve the anti-interference capability of communication and trigger signals by 80%, and to reduce the success rate of electromagnetic interference devices to below 10%, ensuring the long-term effectiveness of the blockade system.
