Abstract: Integrated sensing and communication (ISAC) technology deeply integrates communication and sensing capabilities, and is anticipated to attain seamless communication and sensing coverage for low-altitude flights in critical areas. To fully unleash the potential of ISAC systems oriented towards the low-altitude economy, it is necessary to focus on the key technologies and networking technologies. Beamforming and beam tracking technologies, artificial intelligence (AI)-empowered ISAC technologies, mutual assistance and enhancement between communication and sensing technologies, ISAC technologies based on intelligent reflecting surfaces (IRS), and ISAC networking technologies are systematically described. These key technologies and networking technologies can effectively improve the performance of the ISAC system in low-altitude coverage scenarios.
