In recent times, low-altitude security incidents have continued to occur at a high rate both domestically and abroad, and the situation for low-altitude UAV control has grown increasingly severe. From the UAV electromagnetic-countermeasure confrontations on the Russian-Ukrainian battlefield, to frequent incidents at home involving black-flight UAVs disrupting aviation, park leakage, and airspace intrusions at large events, various modified FPV drones, long-endurance low-altitude aircraft, and intelligent UAV swarms have already become core threats to low-altitude security. As UAV technology becomes more civilian-accessible and modification-friendly, the conventional 2.4G and 5.8G frequency bands traditionally relied on by UAVs are no longer mainstream. A large number of illegal and military-modified UAVs have instead shifted to Sub-GHz ultra-long-range data-link transmission, combined with broadband frequency hopping, multi-link concurrency, spectrum disguise, and dynamic frequency conversion, easily evading the defense range of traditional narrowband detection and jamming equipment. This creates extensive electromagnetic defense blind spots and poses severe safety hazards to key scenarios including military and police security, airport no-fly-zone protection, energy parks, and border defense. The shortcomings of traditional narrowband signal sources — fragmented spectrum, high response latency, inability to simulate complex electromagnetic environments, and weak multi-target countermeasure capability — have become fully apparent, and the industry urgently needs high-performance broadband signal-source equipment to break through the technical bottleneck.
To address the complex and ever-changing low-altitude confrontation scenarios and industry technical pain points of today, our company has focused deeply on the low-altitude security RF technology field. Leveraging years of R&D experience in electronic countermeasures and signal simulation, we have purpose-built and launched our self-developed 400M instantaneous-bandwidth counter-UAV signal source. The equipment focuses on three core requirements — UAV broadband signal simulation, full-domain electromagnetic suppression, and complex environment simulation — breaking through the performance limits of traditional narrowband equipment. With core advantages such as ultra-large continuous instantaneous bandwidth, high-dynamic response, multi-signal compatibility, and compact integration, it comprehensively adapts to all full-scenario applications including counter-UAV equipment testing and calibration, real-combat electromagnetic confrontation, and security drill training, providing core RF support for the next-generation low-altitude counter-UAV system and precisely resolving many of the pain points in existing defense solutions across the industry.
Compared with the conventional narrowband signal sources and multi-segment spliced wideband signal sources on the market, our 400M signal source delivers disruptive performance advantages. The equipment is equipped with a 400MHz ultra-large continuous instantaneous bandwidth, requiring no segmented frequency scanning and no frequency-band switching gaps. It achieves instantaneous signal output across the full spectrum range, completely eliminating the problems of target-signal loss and UAV escape caused by frequency-band switching and spectral discontinuity in traditional equipment. At the same time, the equipment supports multi-dimensional signal simulation, precisely reproducing the remote-control, data-link, and video-link signals of UAVs across the full frequency range — including 433MHz, 900MHz, 1.2G, 2.4G, and 5.8G — while remaining compatible with UAV frequency-hopping, fixed-frequency, and frequency-sweeping signals. It can also simulate complex real-combat electromagnetic environments such as urban building obstruction, electromagnetic clutter interference, and superimposed multi-drone swarm signals, faithfully reproducing real airspace threat scenarios and perfectly solving the industry problems of single-scenario simulation and low practical-combat fidelity in traditional equipment.
At the core performance level, our 400M counter-UAV signal source adopts a self-developed programmable RF waveform algorithm, delivering high signal output precision, low distortion, and microsecond-level dynamic response speed. It can rapidly adapt to countermeasure scenarios involving UAV dynamic frequency conversion and high-speed frequency hopping, precisely capturing and simulating the signals of various unknown modified UAVs. Unlike conventional multi-module spliced solutions, the equipment adopts an integrated, unified design that discards redundant structures, resulting in a smaller footprint, lower power consumption, and greater stability. It supports both fixed deployment in laboratories — used for factory calibration, performance testing, and extreme-condition testing of counter-UAV detection equipment, wideband jamming modules, and RF direction-finding systems — substantially reducing enterprise costs for outdoor real-flight testing and improving product R&D iteration efficiency. It can also be flexibly integrated into vehicle-mounted, fixed, and portable counter-UAV confrontation systems, adapting to real-combat electromagnetic suppression scenarios.
In real-world security applications, leveraging its ultra-large bandwidth advantage, the equipment can achieve full-domain, synchronized blocking jamming across the UAV remote-control link, data-transmission link, and video-transmission link. It can precisely suppress high-risk targets such as long-range Sub-GHz low-altitude UAVs, long-endurance vertical take-off and landing aircraft, and small UAV swarms, effectively compensating for the shortcoming of traditional equipment in failing to jam low-frequency, long-range modified UAVs. At the same time, the equipment supports synchronized multi-target signal simulation and countermeasure scenarios, meeting the needs of military and police real-combat drills, security skills competitions, and airspace emergency-response training. It helps operators become familiar with the signal characteristics of various new UAV types and improves their threat-identification and rapid-response capabilities in complex airspace.
Today, the low-altitude security industry has entered a new stage of “wideband, intelligent, multi-target” countermeasures. UAV threats continue to iterate and escalate, low-altitude electromagnetic environments are growing increasingly complex, and traditional narrowband defense technology can no longer meet the security needs of the new era. Our 400M instantaneous-bandwidth counter-UAV signal source connects the full technology chain of “R&D testing – equipment calibration – real-combat confrontation – drill training,” resolving the industry’s core pain points with hard-core RF performance and filling the market gap for mid-to-high-end wideband counter-UAV signal sources.
Going forward, our company will continue to deepen its focus on the low-altitude electronic countermeasure field, continuously optimizing signal-source waveform algorithms, broadening the compatible frequency range, and advancing equipment miniaturization and intelligent upgrades. We will keep refining product performance to provide more efficient, more stable, and more professional RF core solutions for a full range of key low-altitude security scenarios — including airport no-fly-zone protection, security for large-scale cultural and sporting events, oil-gas and power park security, border airspace control, and classified-area protection — helping to upgrade the domestic low-altitude security system and build a solid full-domain low-altitude electromagnetic security defense line.
