Detection and track processing in Navy AEW Radar is compounded by the rapidly increasing number of wind-farms comprised of multiple turbines. Turbine blades exhibit large reflectivity and occupy portions of the spatial/spectral domain that radar systems have to operate within in order to detect and track mission critical targets (stealthy aircraft, slow-moving drones, numerous surface targets). This mission requires the development of advanced interference-rejection, detection and track processing algorithms. The improved performance of these algorithms comes at a cost - the requirement to better understand all sources of interference. Upstate Scientific proposes to demonstrate an innovative and minimally intrusive Wind-farm Airborne Radar Processor (WARP), to be used for the mitigation of clutter created by the aforementioned wind-farms. The innovation arises in the selection of training data in spatial-temporal filtering, false alarm control, and track processing for the rejection of wind-farm caused clutter and the detection and track processing of targets.
