Patent number: 9291707Abstract: A 3D avian radar sampling system comprises a 3D volume scanning radar system and an avian track interpreter. Scanning methods employed ensure that volume revisit times are suitably short and track data produce 3D target trajectories. The avian interpreter uses the track data from the volume scanning radar to create detailed avian activity reports that convey bird abundance and behavior within a 3D cylindrical volume on intervals including hourly, daily, weekly, monthly and yearly. Hourly activity reports (updated typically every 15 minutes) provide enhanced situational awareness of developing hazards and are actionable, allowing operators to dispatch wildlife control personnel to respond to threats.Type: GrantFiled: September 7, 2012Date of Patent: March 22, 2016Assignee: Accipiter Radar Technologies nc.Inventors: Timothy J. Nohara, Peter T. Weber, Andrew M. Ukrainec, Al-Nasir Premji, Graeme S. Jones, Nelson Costa, Robert C. Beason
