The “silent killer” of low-altitude defense? We’ve built a “wall” that leaves no escape for threats.

Release time:

2025-12-30

Have you ever worried that, at security sites for major events, above critical infrastructure, or in the quiet zones along national borders, those quietly intruding drones—like “silent killers”—render traditional security systems virtually ineffective?

Have you ever worried about those stealthy intrusions—whether at security sites for major events, above critical infrastructure, or in the quiet zones along national borders? Drones are like “silent killers.” Does this render the traditional security system virtually ineffective?

When “ Low, small, slow With their low cost and high stealth, targets can penetrate the limits of physical barriers and human surveillance, turning the invisible boundaries in the sky into the most advanced—and also the most vulnerable—frontier for national and public security. Safeguarding this “invisible” airspace requires not only vigilant eyes but also an “invisible wall”—one that is sharp enough to detect the slightest detail and capable of making wise, informed decisions.

Today, we’re thrilled to unveil the next-generation core that forms the foundation of this intelligent defense system—the XW/SR226 series two-dimensional active pulse Doppler phased-array radar.

01 The foundation of the “wall” stems from a radical revolution against the traditional defense’s “time blind spots.”

Imagine this: Traditional radar, which relies on mechanically rotating scanners, is like a sentinel constantly turning its head—there will always be moments when its line of sight fails to cover certain areas. Yet, drone swarms could precisely exploit these millisecond-long gaps to launch saturation attacks. The XW/SR226 two-dimensional phased-array technology represents a radical breakthrough that addresses this fundamental shortcoming. By abandoning the slow mechanical rotation and instead employing hundreds or even thousands of independent transmit-receive elements, it uses electronic commands to achieve instantaneous, rapid beam steering in both azimuth and elevation dimensions.

This means that it can complete a full-sky scan in just 0.1 seconds, with a data update rate as high as 5 Hz (as in the XW/SR226-8000SD model), enabling a shift from “sequential scanning” to “simultaneous staring.” As a result, “time-difference” attack strategies become completely ineffective, truly achieving foolproof, all-time-domain surveillance.

02 “Seeing clearly” is even more important—intelligent recognition serves as the “brain” of this invisible wall.

Flying birds and drifting debris in the sky often serve as the source of false alarms, consuming valuable security resources. The advanced capability of the XW/SR226 two-dimensional active pulse Doppler multi-array radar lies not only in providing target coordinates but also in endowing it with the ability to identify the intrinsic nature of targets. Its deeply integrated AI-powered processing algorithm can precisely analyze the “micro-motion characteristics” of targets—for example, the fundamental differences between the rotation of a drone’s propellers and the flapping of bird wings as reflected in radar echoes.

Take the XW/SR226-8000SD model as an example: its classification accuracy for drones, birds, and clutter reaches over 95%. This enables the system to automatically filter out irrelevant interference, provide tiered alerts for genuine drone threats, and free operators from tedious, inefficient manual assessments, allowing them to focus on critical decision-making. As a result, the system has made a leap from “information overload” to “cognitive precision.”

03 Faced with a complex environment and diverse missions, we offer customized solutions rather than a single product.

Fully aware of the unique requirements of different scenarios—such as detection range, deployment flexibility, and cost control—XW/SR226’s two-dimensional active pulse Doppler multi-aperture radar has established a product matrix with clearly defined layers, much like “bricks” custom-made for different segments of the defense line.

Agile “Frontline Sentinel” XW/SR226-6000XD:

This four-sided radar, operating in the X-band and weighing no more than 40 kg, is a prime example of rapid response and mobile deployment. It boasts a detection range of up to 5 kilometers (for targets with an RCS of 0.01 m²) and can be quickly set up by a single operator, with power consumption below 1,400 watts. Like a keen “electronic sentry,” it is particularly well-suited for frontline positions requiring flexible deployment—such as border patrols, temporary critical sites, and base perimeters—enabling high-density, blind-spot-free surveillance of micro drones.

Balanced “Regional Pillar” XW/SR226-5000SA:

Employing the S-band, this system strikes an ideal balance between detection performance and cost-effectiveness. It can detect small drones (RCS = 0.01 m²) at a range of ≥5 kilometers, and its detection capability for larger targets exceeds 25 kilometers. This system perfectly embodies the core attributes of “fast, intelligent, accurate, and stable,” serving as a reliable backbone for building regionalized, normalized low-altitude surveillance networks. It is ideally suited for applications such as urban security, airport airspace protection, and industrial park monitoring.

The powerful “intelligent hub” XW/SR226-8000SD:

This represents the technological pinnacle of the series. It employs S-band all-digital active phased-array technology, supporting 128 parallel channels and 16 independent beams, with a detection range spanning from 8 kilometers (for micro drones) to 15 kilometers. Its revolutionary “software-defined radar” concept, combined with an ultra-low-cost modular design, significantly reduces system costs while endowing it with the “life force” of continuous evolution through software upgrades. It serves as a “brain-like” piece of equipment for intelligent, networked defense of large-scale critical infrastructure, core command nodes, and vast border and maritime areas.

04 True reliability is the combat capability that can consistently deliver results even under extreme conditions.

All outstanding performance parameters must withstand the rigors of harsh environments. The XW/SR226 two-dimensional active pulse Doppler multi-array radar products feature an extended operating temperature range from -40°C to +55°C and a high IP67 protection rating. Whether facing the wind and sand of northern deserts, salt spray in the South China Sea, or electromagnetic interference in urban areas, these radars can operate reliably under all conditions. From the compact 6000XD to the powerful 8000SD, their modular design and low maintenance requirements ensure high reliability and availability even in challenging field and vehicle-mounted applications, turning theoretical performance into a dependable safeguard that is ready for deployment anytime, anywhere.

05 The power of a single “wall” is limited, but a smart wall that can seamlessly connect with other defensive lines will forge the strength of an entire system.

The standardized data interface (RJ45 100-Mbps Ethernet) enables seamless integration with optoelectronic tracking systems, navigation deception or jamming devices, and integrated command-and-control platforms. Once the radar detects and identifies a threat, it can instantly provide precise guidance to the optoelectronic system, achieving synergistic cooperation between "long-range radar detection and precision optoelectronic confirmation." Additionally, target information can be实时ly distributed to interception units, forming an integrated closed-loop system encompassing "detection, control, defense, and management." Multiple radars can also be flexibly networked to build a three-dimensional sensing network with broader coverage and enhanced resilience against disruption.

From safeguarding the strategic frontiers of national security to protecting the sensitive airspace that ensures the smooth operation of cities, low-altitude safety has become a new issue of critical importance to both the nation’s economic and social well-being. Choosing a high-performance radar system is, in essence, embracing a forward-looking, systematic approach to low-altitude security defense. The “speed” of electronic scanning meets the “agility” required to counter drones; the “intelligence” of AI-based recognition tackles the “clutter” caused by mixed targets; the “precision” of tailored solutions aligns with the “diverse needs” of various scenarios; and the “stability” of robust materials supports the “heavy burden” of round-the-clock missions.

This “invisible wall,” forged by technology, is quietly expanding the boundaries of our safety, ensuring that every sky worthy of protection remains clear and serene.
