  Unmanned aerial vehicle (UAV)-enabled integrated sensing and communication
(ISAC) has attracted growing research interests in the context of
sixth-generation (6G) wireless networks, in which UAVs will be exploited as
aerial wireless platforms to provide better coverage and enhanced sensing and
communication (S&C) services. However, due to the UAVs' size, weight, and power
(SWAP) constraints, controllable mobility, and line-of-sight (LoS) air-ground
channels, UAV-enabled ISAC introduces both new opportunities and challenges.
This article provides an overview of UAV-enabled ISAC, and proposes various
solutions for optimizing the S&C performance. In particular, we first introduce
UAV-enabled joint S&C, and discuss UAV motion control, wireless resource
allocation, and interference management for the cases of single and multiple
UAVs. Then, we present two application scenarios for exploiting the synergy
between S&C, namely sensing-assisted UAV communication and
communication-assisted UAV sensing. Finally, we highlight several interesting
research directions to guide and motivate future work.
