Implication

Randomized trial demonstrates robust UAV detection under severe noise and clutter conditions, indicating enhanced reliability.

Key Points

This research aims to develop a framework for detecting hovering UAVs in challenging environments dominated by noise and clutter.
Developed a micro-Doppler flash detection framework with three modules: PTOP for clutter suppression, flash power spectrum construction, and CA-CFAR for reliable detection.
Applied simulations with signal-to-clutter ratio of −21 dB and signal-to-noise ratio of −23 dB to test performance.
Utilized Gabor transform and fast Fourier transform to enhance detection capabilities.
Framework reliably detects UAVs despite obscured micro-Doppler signatures, demonstrating it can operate effectively under challenging conditions.
Achieved accurate detection reflected in parametric SNR sweep curves and 2D detection-probability heatmap.
Conventional methods showed severe performance degradation compared to the proposed framework.
