Ⅰ. System Positioning: The Core Perception Node for Countering Future Low-Altitude Threats
In the field of low-altitude security, early, precise, and reliable situational awareness is the cornerstone of an effective response. The YFR-03B-Ku radar system is built for this very purpose. Utilizing Ku-band and advanced DBF (Digital Beamforming) technology, it is specifically designed for Low-altitude, Slow-speed, Small (LSS) targets. It doesn't just "see"—it "clearly identifies" and "firmly tracks", serving as the front-end perception core for building a regional-level low-altitude defense system.
Ⅱ. Core Value: Providing Comprehensive, High-Confidence Protection for Critical Areas
Precise Insight, First-to-Detect: For micro targets with an RCS of only 0.01m², the detection range in normal mode can reach 5 km, securing precious early warning and decision-making time for the defense system.
Keen-Eyed, Intelligent Discrimination: With azimuth accuracy as high as 0.3° and range accuracy of 6 meters, it enables centimeter-level target positioning. Combined with built-in AI algorithms, it can intelligently classify "UAVs" vs. "Birds/Other", significantly reducing false alarm rates and ensuring efficient and accurate command decisions.
On-the-Move Detection, Flexible Deployment: Supports operation on mobile platforms. Combined with automatic calibration, it achieves "deploy-and-use, scan-on-the-move", perfectly fitting the needs of mobile missions like vehicle-mounted patrols, shipboard protection, and temporary site fortification.
Stable Performance in Complex Countermeasures: Features an advanced built-in anti-jamming processing module that effectively counters common active deception and passive clutter interference. The unique "Sector-based Electromagnetic Silence" function can avoid interference from friendly or own electronic equipment in specific directions, ensuring stable output of high-quality tracks in complex electromagnetic environments.
Comprehensive Data, Empowering Decision-Making: The system completely records plot, track, and device status data, and supports post-mission playback and analysis. This is not only useful for mission debriefing and tactical optimization but also provides critical data support for forensic investigation and threat traceability.
Ⅲ. Key Technology Capability Matrix
| Capability Dimension |
Performance Metric |
Scenario Interpretation |
| Detection Power |
5km (RCS 0.01m²) |
Provides sufficient warning depth for core facilities (e.g., airport clearance zones, nuclear power plants, government compounds), enabling early detection of targets like consumer-grade UAVs. |
| Positioning Accuracy |
Azimuth ≤0.3°, Range ≤6m |
High-precision 3D coordinate output is the prerequisite for guiding EO/IR systems for target identification, laser weapons for precise strikes, or navigation spoofing systems for area denial. |
| Environmental Adaptability |
Operating Temp: -40℃~+65℃
Protection Rating: IP65 |
From extreme cold to intense heat, from sandstorms to rain, ensures stable, uninterrupted 24/7 operation in most of the world's harshest environments. |
| Platform Adaptability |
On-the-Move Operation, Auto-Calibration |
Breaks the limitations of fixed deployment, allowing rapid integration onto various mobile platforms for quick response and escort protection of key routes, borders, or emergencies. |
| Target Processing |
Classification & Identification, Anti-Jamming |
Effectively distinguishes target types in airspaces with mixed birds and UAVs (like airports, cities), avoiding false alarms and improving defense efficiency and cost-effectiveness. |
Ⅳ. Typical Application Scenarios
Point Defense/Area Defense: Protecting sensitive areas like party, government; nuclear power plants; oil storage depots.
Border and Coastline Surveillance: Countering illegal cross-border activities like low-altitude infiltration and smuggling.
