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.\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"mso-bookmark: 设备名称;\"\u003e\u003cspan lang=\"EN-US\" style=\"font-family: 'Times New Roman',serif;
