Passive Radio

Passive radio technology uses ambient radio frequency signals to detect and locate objects or individuals without requiring them to carry electronic devices. Current research focuses on improving the accuracy and robustness of these systems, particularly through the development of advanced signal processing techniques, such as multi-antenna array processing and ensemble learning methods for improved 3D positioning, and data fusion with other sensor modalities like electro-optical imagery for enhanced object identification and tracking. This technology holds significant promise for applications ranging from indoor positioning and security surveillance to drone detection and management, offering a cost-effective and privacy-respecting alternative to active sensing methods.
