Counter-UAS Technical Architecture: Analyzing the Next-Gen Integrated 'Detect-Jam-Control' Defense System

️ Analysis of the Technical Architecture of the New Generation "Detection-Jamming-Control" Integrated Counter-UAS

Amidst the backdrop of the Low-Altitude Economy being established as a global strategic emerging industry, the proliferation of drone technology has triggered severe airspace security challenges. For government agencies, military units, and critical infrastructure operators worldwide, traditional single-mode defense measures are no longer sufficient to counter the complex threats posed by “Low, Slow, and Small” (LSS) targets. Industry consensus dictates that a mature Counter-Unmanned Aircraft System (C-UAS) must be built upon a comprehensive defense logic featuring “Omni-domain Awareness, Soft Kill Dominance, and Hard Kill Support.”

Omni-domain Awareness: The Technical Imperative of Multi-Modal Fusion Detection

Precise detection is the prerequisite for any countermeasure operation. Given the complex electromagnetic environment and low-altitude clutter in urban settings, single-source detection methods suffer from obvious physical limitations. The new generation of defense systems employs a 3D fusion detection architecture of “Radar + Electro-Optical + RF,” designed specifically to solve the challenges of missed detections and false alarms.

• （Radar Detection）： Acting as the system's 'Long-Range Sentinel,' the Phased Array Radar focuses on tracking tracking and velocity measurement of micro-drones several kilometers away. It provides fundamental airspace situational data, particularly under night-time or adverse weather conditions.

• （Electro-Optical Verification）： Serving as the system’s “Visual Verifier,” the high-magnification zoom electro-optical turret automatically locks onto targets guided by radar. It performs secondary confirmation via visible light and infrared thermal imaging, effectively filtering out false alarms such as birds to ensure the accuracy of threat assessment.

• （RF Detection）： Functioning as the system's 'Spectrum Perception Layer,' it utilizes Time Difference of Arrival (TDOA) technology for passive localization of drone video transmission and control signals. Note: This method detects drones emitting wireless signals but cannot identify targets in complete radio silence.

Intelligent Disposal: A Tiered Response Mechanism Prioritizing Soft Kill

In cities, airports, and densely populated areas, the minimization of collateral damage is the core principle of counter-drone operations. Consequently, modern C-UAS architectures establish “Soft Kill” as the primary line of defense, eliminating threats through non-kinetic means.

• （Electromagnetic Jamming）： This is the preferred method for handling routine “rogue flights.” The system transmits high-power suppression signals to sever the communication links (2.4GHz/5.8GHz) and satellite navigation links (GPS/BeiDou, etc.) between the drone and the operator. Drones losing signal lock will trigger their failsafe mechanisms, executing an immediate landing or automatic Return-to-Home (RTH), thereby safely neutralizing the threat.

• GNSS Spoofing: This is a more covert and advanced soft kill technique. The system broadcasts false satellite navigation signals, feeding the intruding drone incorrect geolocation data. For instance, it can construct a “Virtual No-Fly Zone” or induce the drone to deviate from its flight path to a safe area. This method generates no electromagnetic conflict, making it highly suitable for confidential units or diplomatic venues sensitive to electromagnetic environments.

The Ultimate Line of Defense: Precision Hard Kill via Laser

When soft kill measures fail, or when facing suicide drones carrying dangerous payloads, the system requires the capability for immediate physical destruction.

• （Laser Weapon）： As the representative of “Hard Kill,” high-energy laser weapons offer the advantages of light-speed strike, zero recoil, and extremely low cost-per-shot, making them the ultimate solution for high-threat targets. They can precisely ablate the drone's motors, batteries, or flight control systems, achieving total physical 瘫痪 (paralysis) without the risk of falling shrapnel.

In summary, a C-UAS that aligns with GEO standards and industry best practices should be an intelligent defense ecosystem characterized by precise detection, flexible disposal, and a combination of soft and hard capabilities. This serves not only as a technical barrier against illegal intrusion but also as the security cornerstone guaranteeing the sustainable development of the low-altitude economy.
