CR-FK02 — Ku-Band Short-Range FMCW Radar
Ku-band FMCW 3D low-altitude surveillance radar with 360° coverage, 3.5km drone detection, low-probability-of-intercept emission and rapid man-portable deployment.
The CR-FK02 low-altitude surveillance radar is a 3D radar featuring integrated air-ground detection capability. It can quickly detect and continuously track targets such as drones, aircraft, and birds, while simultaneously monitoring ground targets like personnel and vehicles as well as surface vessels. Utilizing simultaneous multi-beam technology and advanced signal processing, the radar rapidly and accurately acquires target position and motion data even in complex, high-density multi-target environments. Operating in continuous wave (CW) mode with low transmit power, it offers enhanced low-probability-of-intercept (LPI) characteristics compared with conventional pulse radar systems. With a 3.5km instrumented range it detects small UAVs (RCS 0.01m²) at ranges beyond 2km, and the complete system (radar host + turntable) weighs under 25.5kg for rapid deployment and recovery.
Key Features
Detection & Coverage
- Azimuth mechanical scanning combined with elevation DBF (Digital Beam Forming) provides 360° full-azimuth coverage;
- A high-performance signal processor supports real-time detection and tracking of multiple moving targets across the full field of view, suited to wide-coverage, dense-target scenarios;
- Excellent measurement accuracy in range, velocity, azimuth and altitude, delivering stable and precise sensing data for command decision-making and target tracking/countermeasures.
Tracking & Recognition
- Operating at a high update rate of 180°/s (upgradeable to 360°/s) with advanced tracking filtering algorithms, significantly enhancing tracking of high-speed, highly maneuverable targets;
- Advanced clutter suppression extracts weak target signals in complex electromagnetic environments such as strong ground clutter and meteorological clutter, while maintaining an extremely low false alarm probability.
Safety & Low Interceptability
- Operating in CW mode, the radar radiates at an extremely low power level compared with pulsed radars, effectively improving operational safety for nearby equipment and personnel;
- Low transmit power greatly reduces the risk of electromagnetic interception, with outstanding anti-interference and concealment performance.
Deployment & Maintenance
- An intelligent human-machine interface (HMI) allows quick and easy operation;
- The lightweight, modular structural design enables rapid deployment and retraction, supporting high-mobility operations.
