説明

<p>This letter investigates a secrecy rate maximum optimization problem of unmanned aerial vehicle (UAV) system with integrated sensing and communication (ISAC) function. To ensure the security of the ISAC-UAV system, we formulate a joint UAV trajectory and transmit power optimization problem to maximize the secrecy rate under the constraints of mobility restrictions, power budgets and sensing requirement. The block coordinate descent (BCD) method is employed to divide the original problem into two sub-problems. Then, the non-convex sub-problems are transformed to convex by the appropriate constraints relaxation and fractional programming method. Eventually, the simulation results verify the effectiveness of our proposed algorithm and demonstrate the trade-off performance between the secrecy and sensing.</p>
