Abstract: Embodiments described herein provide for the improved detection of target(s) in the vicinity of cluttered environments such as wind farms, and for the reduction of false alarms resulting from wind turbines and other complex structures in such environments. Maximum amplitude readings of all non-zero Doppler frequency bins are determined for each resolution cell under test during a dwell and used to determine an aggregate threshold value. In one embodiment, the aggregate threshold value and an existing threshold value are compared and the higher value applied. A tracking sample period and a transition state delay are introduced to determine when the aggregate threshold value for each resolution cell under test should be updated.

Abstract: A device and method to suppress clutter generated by stationary targets that also have moving components that give significant Doppler returns when scanned by radar, such as wind turbines.
