Using Radar Cross-Section to Enhance Situational Awareness Tools for Airport Avian Radars
Human-Wildlife Interactions, 2017 Digital avian radars can track bird movements continuously in the vicinity of airports without interruption. The result is a wealth of bird-track data that can be used in mitigation efforts to reduce bird strikes on and near airfields.

Radar orthogonality and radar length in Finsler and metric spacetime geometry [PDF]
, 2014 The radar experiment connects the geometry of spacetime with an observers measurement of spatial length. We investigate the radar experiment on Finsler spacetimes which leads to a general definition of radar orthogonality and radar length. The directions
