Portable UAV Spectrum Detection & Control Unit | Handheld/Backpack Dual Mode | 20MHz–6GHz Wideband | Detect-Respond-Redirect All-in-One

Ⅰ. Product Overview

The LKLT-PDJ420 is a portable UAV spectrum sensing and management device designed for low-altitude airspace security applications. It features a dual-configuration form factor—handheld pistol-grip or backpack carry—allowing operators to switch configurations based on field requirements. The system integrates three core modules: passive wideband spectrum sensing, frequency overlay, and flight-path guidance, covering 20 MHz to 6000 MHz. It can simultaneously identify RF signals from 100+ airborne targets and precisely recognize mainstream brands including DJI at a detection range of up to 3 km. Flight-path guidance distance is continuously adjustable from 10 m to 1000 m to accommodate varying operational radii. System response time is under 5 seconds. The unit supports continuous unattended operation with built-in multi-channel alert mechanisms, making it suitable for mobile low-altitude airspace management at sporting events, exhibitions, and critical facility perimeters.

Ⅱ. Product Selling Points

Ultra-wideband spectrum sensing: 20 MHz – 6000 MHz full coverage, simultaneous identification of ≥100 targets, DJI-series detection range ≥3 km

Tri-mode integrated response: detection, frequency overlay, and flight-path guidance in one unit; response time <5 s

Dual-form portable design: handheld pistol-grip or backpack-carry configuration; single-operator rapid deployment

Adjustable guidance range: 10 m – 1000 m continuously tunable, suitable for close-range and mid-range scenarios

Low false-alarm unmanned operation: intelligent false-alarm suppression, continuous unattended monitoring, multi-channel alerts (audio / visual / network push)

Ⅲ. Technical Specifications

Ⅳ. Performance Introduction

This anti drone detector jammer covers ultra-wide 20MHz~600oMHz frequency band, capableof identifying more than 100 drones at the same time with max 3km detection distance for DJI series drones and low false alarm rate. Its jamming range hits 2km while spoofing distancecan be freely adjusted within 10m-100om, and the whole countermeasure response is lessthan 5s. Adopting lightweight dual-form factor design, the device supports fast deploymentand high-speed moving operation equipped with multi-type intelligent alarm functions torealize long-term unattended monitoring for continuous low-altitude protection

Ⅴ. Multi-scenario Application

1. Airport & civil aviation restricted airspace: Block illegal drones to eliminate flight safetyhidden dangers
2. Border checkpoint, camp: Mobile patrol anti drone interception and expulsion
3. Large conferences sports events, exhibition venues: Temporary portable low-altitudedefense
4. Prison confidential factories government buildings: Prevent aerial surveillance and secretleakage
5. Oil fields, power stations and key energy facilities: Stop illegal drone intrusion
6. Mobile law enforcement patrol field security duty: Flexible handheld & backpack deployment
