    Main Features

    • 1
      It has all-weather and all-time detection, tracking, identification and alarm, and has the ability to detect and monitor multiple batches and targets at the same time.
    • 2
      High accuracy and long detection range: the radar actively detects, obtains the target's azimuth, distance, speed and other information, filters out the interference of the environment and small animals through the target characteristic parameters, and further reduces the probability of false alarms and missed alarms.
    • 3
      It has multi-layer prevention and control area setting function, and can distinguish the danger level from far and near for refined early warning.
    • 4
      It has a real-time output function of target angle, distance and other information.
    • 5
      The system has self-check function and real-time monitoring function of equipment status during operation, ensuring that users can always keep abreast of the online or fault situation of equipment.

    Application Scenarios

    Border Ports Port Terminals Chemical Industrial Parks

    Designed specifically for ground/water surveillance of critical targets such as chemical industrial parks, border ports, and port terminals. It enables comprehensive monitoring, early warning, and tracking of personnel, vehicles, and vessels under all-weather conditions.

    Frequently Asked Questions

    Q
    What types of targets can the LJ-E01 Ground Surveillance Radar detect?
    The LJ-E01 can detect and recognize pedestrians and vehicles/vessels. Its maximum detection range reaches ≥1000m for pedestrians and ≥2000m for vehicles and vessels, making it well-suited for wide-area perimeter protection at borders, ports, and industrial facilities.
    Q
    What frequency band does the LJ-E01 radar operate in, and why does it matter?
    The LJ-E01 operates in the K-band frequency range, which provides excellent sensitivity and spatial resolution for detecting small, slow-moving targets such as pedestrians at ground level, while maintaining reliable range performance for larger vehicle-class targets.
    Q
    Can the LJ-E01 operate continuously under all weather conditions?
    Yes. The LJ-E01 is engineered for 24/7 all-weather, all-time operation. Rain, fog, dust, and complete darkness do not impair its detection performance, ensuring uninterrupted perimeter security coverage across all environmental conditions.
    Q
    What azimuth coverage does the LJ-E01 provide, and can it be expanded?
    A single unit covers a 90° azimuth angle. Coverage can be expanded to 180°, 270°, or full 360° by deploying two-sided, three-sided, or four-sided array configurations respectively. The elevation angle is fixed at 18°.
    Q
    How does the LJ-E01 reduce false alarms caused by animals or environmental clutter?
    The system employs adaptive clutter suppression technology combined with target characteristic parameter filtering. This distinguishes genuine intrusion targets (pedestrians, vehicles) from non-threat sources such as small animals or environmental interference, significantly lowering both false alarm and missed alarm rates.
    Q
    What real-time data does the LJ-E01 output for each detected target?
    The LJ-E01 delivers real-time per-target data including azimuth angle, range (accuracy <10m), and velocity (accuracy <0.5m/s), updated at 0.5Hz. Data is transmitted via standard IP network interface (DC12V power supply), allowing straightforward integration with existing security management platforms.
