Secrecy Enhancement for AAV-Enabled Integrated Sensing and Communication Systems

In this letter, we propose a AAV-enabled integrated sensing and communication (ISAC) system for secrecy enhancement, where a full-duplex AAV with a uniform planar array serves multiple ground users while sensing and jamming a ground eavesdropper. To maximize the sum secrecy rate under sensing SINR and operational constraints, we jointly optimize the transceiver beamforming and AAV trajectory. An algorithmic solution based on block coordinate descent (BCD) and semidefinite programming (SDP) relaxation technique is developed, whose performance gains are emphasized in simulations with sufficient mission periods.
