Bird or Drone? The Hardest Classification Problem in Counter-UAS Isn't the One You'd Expect
This article is about why a bird and a drone are so hard to tell apart, the handful of physical signatures we can actually exploit, etc.
Counter-drone systems often have advanced technology, but they can be easily fooled by birds. This classification problem is the most significant challenge in counter-unmanned aircraft systems (C-UAS). While humans can easily distinguish a bird from a drone, automatically differentiating between them from a small pixel smudge half a mile away is difficult. The consequences of misidentifying either a bird or a drone are costly and can determine whether a system is deployable.
