摘要
针对由相控阵雷达和多用户多输入多输出(Multiple-Input Multiple-Output,MIMO)通信系统组成的雷达通信共存架构,为消除系统间的干扰,提出一种遍历干扰对齐算法。利用这种方法可以有效地消除相控阵雷达和MIMO通信系统之间的相互干扰,且可以利用相控阵雷达的相干累加特性提高雷达系统的检测性能。分析了通信干扰对相控阵雷达系统的影响,并推导出相应的检测概率。理论分析和仿真结果都验证了遍历干扰对齐方法的有效性。
An ergodic interference alignment(IA)method is proposed for interference elimination in co-existing radar-communication systems that consists of a phased array(PA)radar and multi-user multiple-input multiple-output(MIMO)communication system.With this method,the mutual interferences between PA radar and MIMO communications can be efficiently eliminated and the coherent accumulation characteristic of PA radar can be exploited to improve the detection performance.The effect of communication interference on PA radar is investigated and the corresponding detection probability is derived.Both theoretical analysis and simulation results validate the effectiveness of the proposed co-existing radar and communication system.
