SF-X20 Low-Altitude Surveillance Radar
Product Introduction

The LT-X20 low-altitude surveillance radar is mainly used for low-altitude and ground monitoring.

It adopts a digital beamforming (DBF) architecture, offering high beam-agility efficiency and high search-data throughput.

With adaptive clutter-suppression technology and dense target detection & pre-tracking algorithms, the radar achieves extremely low false-alarm rates and is capable of automatically tracking over 500 targets, outputting high-precision localization information.

Equipment Features
  1. High accuracy.
  2. Wide coverage area.
  3. Immediate target detection and tracking.
  4. Digital beamforming architecture with high search-data throughput.
  5. Wide detection velocity range.
  6. Excellent clutter and false-alarm suppression capability.
  7. Large-area coverage:
    Azimuth coverage 360°, elevation coverage > 60°.
  8. Outputs the position and speed information of moving targets within the radar scanning area.
  9. Supports automatic indication of target motion trajectories.
  10. Adaptive clutter filtering, ensuring effective suppression of ground clutter, water clutter, and atmospheric clutter while maintaining stable tracking.
  11. Supports data recording and playback.
