Portable Backpack RF Spectrum Sensor 3km Long Range Multi Band Perimeter Security Low Altitude Drone Detection System

Ⅰ. Product Overview

The LKLT-BDJ410 is an industry-leading portable backpack drone detection system and low-altitude airspace security system engineered specifically for high-mobility perimeter security and critical infrastructure protection. By seamlessly combining cutting-edge passive RF spectrum sensors, omni-directional RF signal management, and precision GNSS navigation guidance, the LKLT-BDJ410 establishes a robust, non-destructive low-altitude security perimeter—delivering seamless capabilities from early intrusion warning and radio protocol fingerprint identification to decisive, non-kinetic target mitigation.

Engineered for challenging outdoor mobile patrol, the LKLT-BDJ410 features a lightweight ergonomic backpack design with a total weight of ≤ 13 kg. Its advanced passive radio frequency receiver achieves an outstanding 3 km detection range, tracking ≥ 20 targets simultaneously with a rapid response time of ≤ 3 seconds and a detection success rate of ≥ 99%. In active countermeasure mode, the device provides 1 km omni-directional RF coverage across critical operational frequencies, providing dependable protection against multi-rotor UAVs, high-power drones, and advanced 4G/5G cellular-linked aircraft.

Powered by a high-capacity internal battery offering ≥ 8 hours of continuous passive monitoring and ≥ 1 hour of active defense (rechargeable in ≤ 3 hours), and paired with rugged tablets for real-time situational tracking, the LKLT-BDJ410 provides turnkey perimeter intrusion detection for petrochemical refineries, electrical power substations, civil aviation perimeters, border corridors, and large-scale commercial event security.
