The rotation of rotor blades on small unmanned aerial vehicles (UAVs) introduces micro-Doppler (m-D) signatures to discriminate UAVs from other aircrafts or ...

In this paper, the authors deploy local mean decomposition (LMD) to separate the m-DS of the micro-motion parts from the body returns of the UAVs and birds.

The cyclostationary phase analysis (CPA) is proposed to estimate the m-D parameters for radar detection of small UAVs, which could simplify the procedure of ...

Sep 15, 2023 · In this paper, a clutter suppression method based on an orthogonal matching pursuit (OMP) algorithm is proposed, which is used to process echo signals.

The radar uses micro-Doppler effect to detect the micromotion characteristics of small UAV rotors, which can be extracted by a quadrature-phase detector. The ...
