Integrated sensing and communication (ISAC) for unmanned aerial vehicle (UAV) swarms, as a core technology of 6G space-air-ground integrated networks, significantly enhances the system efficiency of low-altitude economic and military applications by integrating sensing and communication functions. This paper studies the current status and future challenges of ISAC for UAV swarms from three aspects: physical layer transmission, beamforming and networking, and multi-task joint scheduling. In the future, it is necessary to deeply integrate estimation theory, optimization algorithms, and AI methods to break through the bottlenecks of physical layer dynamic modeling, intelligent networking, and joint sensing and communication scheduling for swarm ISAC, and promote the systematic implementation of low-altitude economic and defense applications.
