Efficient Multipath Clutter Cancellation for UAV Monitoring Using DAB Satellite-Based PBR

The increasing accessibility of unmanned aerial vehicles (UAVs) drives the demand for reliable, easy-to-deploy surveillance systems to consolidate public security. This paper employs passive bistatic radar (PBR) based on a digital audio broadcast (DAB) satellite UAV monitoring in applications with power density limitations electromagnetic radiation. An advanced version extensive cancellation algorithm (ECA) data segmentation and coefficients filtering is designed improve efficiency multipath clutter suppression while retaining robustness, which effectiveness verified by theoretical derivation simulation. detectability small UAVs DAB satellite-based PBR validated experimental results, influence target altitude geometry are also analyzed.
