1. Introduction

With the rapid development and popularization of drone technology, drones have shown great application potential in aerial photography, agriculture, rescue, security and other fields, but at the same time they have also brought increasingly serious safety risks. Incidents such as illegal intrusions, malicious reconnaissance, and privacy violations occur frequently, posing serious threats to national security, public safety, and personal privacy. Therefore, the development of efficient and advanced drone jamming technology has become an urgent need to maintain airspace security and ensure social stability.

Note:The wristband is optional and can be selected by users as needed.

2. Device Overview

The portable drone detection device primarily consists of a detection host and a wristband information receiving terminal. It integrates spectrum sensing technology and offers reconnaissance, control display, and team coordination functions. The device can effectively detect and identify various types of drones and send alarm signals. It employs low-power, ultra-wideband digital reception technology, signal detection algorithms, and drone identification algorithms, paired with an external high-efficiency ultra-wideband antenna. In complex electromagnetic environments, it can accurately identify quadcopters, fixed-wing drones, DIY models, and FPVs, providing audible, visual, and vibration alerts.
