Multi-User and Multi-Target Constant Waveform Design of Dual-Function Radar and Communication System

  • 摘要: 双功能雷达通信一体化系统可以使硬件和频谱资源得到有效利用,是解决当前无线频谱资源紧张问题的一种有效途径。该文针对同时多目标探测与多用户通信场景,以雷达接收回波的信干噪比(SINR)为指标保障雷达的探测性能,采用通信多用户干扰(MUI)作为通信指标保证通信传输性能。与此同时,为保证发射端功率放大器工作在饱和区域,增加了波形恒模的约束条件。该文通过对波形以及滤波器的联合优化,提出了一种在满足通信MUI功率一定的情况下,最大化雷达多目标探测回波最小信干噪比(SINR)的波形设计优化模型。针对此优化问题,采用了交替迭代优化的方法来求解此问题。仿真结果表明,所设计的波形在多目标探测以及多用户通信场景下,通过调整通信MUI功率门限,可以在保证通信MUI功率性能前提下,实现对多目标回波最小SINR的优化。
