UAV Micro-Doppler Signature Analysis

The radar phenomenology of UAVs interacts with the micro-Doppler signal processing in interesting and useful ways. This paper adjusts the micro-Doppler processing to establish more consistent UAV micro-Doppler signatures and improve the separability of relevant features. The outlined approach is developed in the context of UAV rotor analysis. The techniques are demonstrated in both simulated and experimentally measured results of UAV rotor blades to distinguish three different types of UAV.
