Multi-band portable backpack drone jammer - wrist-worn integrated design

The wristband control panel integrates a high-definition touch display and easy-to-use buttons, providing real-time information on multi-band interference, target distance and direction, remaining battery power, and operating mode. Operators can initiate emergency blocking with a single button or switch modes and power levels by sliding. The wristband supports haptic feedback and visual alarms, facilitating rapid decision-making and coordinated command in complex outdoor environments.

The device employs GPS and BeiDou dual-mode fusion positioning, achieving centimeter-level to meter-level target positioning accuracy through multi-source satellite data and filtering algorithms. After fusion, it can quickly lock onto the trajectory of moving drones, estimate flight altitude and speed, and transmit location information back to the wristband and ground station. It supports trajectory playback and event recording, significantly improving the accuracy of interception and targeted hits.

The backpack features quick-release shoulder straps and adjustable chest and waist belts, combined with contoured pressure-reducing shoulder pads and a breathable back panel to distribute weight and reduce shoulder and back pressure. The quick-assembly design facilitates rapid deployment or short-term carrying by a single person. Modular attachment points support external batteries or tool bags, suitable for extended field inspections and emergency use.

It incorporates a low false alarm rate recognition algorithm, based on a classifier trained with multi-dimensional features (spectrum, impulse model, flight trajectory, and acoustic/optical assistance), effectively distinguishing between normal civilian drones, industrial drones, and non-threat targets such as flocks of birds. The algorithm supports online learning and threshold adaptation, reducing the risk of false alarms to normal flight activities and ecological disturbances.
