This UAV detection and countermeasure system integrates the functions of UAV identification, positioning, neutralization and management in one. Based on technologies including spectrum sensing, message parsing and RID identification, it realizes functions such as early warning, identification, positioning and tracking of UAVs. Leveraging radio electronic countermeasures and GNSS spoofing technology, it achieves the neutralization effects of repelling, forcing to land and decoying target UAVs. It is designed to protect key areas from UAV threats.
