Abstract

In this work, we consider the detection of communication activity from unmmand aerial vehicles (UAV s). For the first time, we design the detector from the protection perspective of a radio frequency (RF)-based detector at ground to detect UAV communication activity with a finite blocklength. Specifically, we derive a closed-form expression for the detector's detection error probability with the prior probabilities to evaluate the detection performance. Then, we propose a lightweight threshold-based (LTB) scheme based on an average received power test to minimize the blocklength subject to a detection performance requirement. To mitigate the sensitivity of the LTB scheme, we further propose a lightweight naive Bayes (LNB) scheme based on the continuity of the UAV communication activity at the cost of a slight increase of the blocklength, where the derived detection performance can be used to leave out the collection of the training dataset. Meanwhile, numerical results demonstrate the advantages of the proposed two schemes over the naive Bayes scheme, in terms of achieving a lower computational complexity.
