Micromotion Feature Extraction with VEMW Radar Based on Rotational Doppler Effect

Remote Sensing, 2023
Micro-Doppler (m-D) analysis is the most effective mechanism for detecting rotating targets or components; however, it fails when the target rotation plane is perpendicular to the radar line of sight (LOS). The vortex electromagnetic wave (VEMW) provides
