研究了无人机合法监控通信系统。具体来说，合法的全双工（FD）无人机监视器窃听可疑地面发射机发送的信息，同时干扰可疑接收机。考虑到飞行时间的有限性，以最大化平均可达监视率（AASR）为目标，联合设计无人机航迹，自适应控制对可疑链路的干扰功率。我们制定的优化问题的基础上的监视状态在不同的飞行阶段，并提出了一个两阶段的迭代算法与逐次凸逼近（SCA）和块坐标下降（BCD）的方法，以获得一个有效的次优解。仿真结果验证了该方法的有效性和优越性。
This paper investigates the unmanned aerial vehicle (UAV) legitimately monitoring communication system. Specifically, a legitimate full-duplex (FD) UAV monitor eavesdrops the information sent by a suspicious ground transmitter while jams the suspicious receiver simultaneously. Considering the limited flight time, we jointly design the trajectory of UAV and adaptively control the jamming power on the suspicious link to maximize the average achievable surveillance rate (AASR). We formulate the optimization problem based on the surveillance state in different flying phases and propose a two-stage iterative algorithm with successive convex approximation (SCA) and block coordinate descent (BCD) methods to obtain an efficient suboptimal solution. The simulation results validate the effectiveness and superiority of the proposed scheme comparing with the traditional method.
