摘　　要：为了实现多个电子平台的高效集成,同时缓解无线信道频谱资源紧缺问题,提出了一种结合了时间调制阵列(time-modulated array,TMA)技术和多波束赋形技术的空域多波束雷达通信一体化结构与算法。对传统基于空分的雷达通信一体化技术进行了改进,在增加通信波束的同时,实现了雷达与通信子系统发射功率的独立控制。所提结构由两组加权网络组成,第一组加权网络用于雷达探测,第二组加权网络结合周期性时间调制,用于多用户通信。所提方案可根据实际应用情况,在用户数量,波束控制自由度,硬件复杂度等多个指标之间进行权衡。仿真结果证实了所提结构与算法的有效性,雷达与通信能够独立完成各自的功能且没有相互影响。In order to achieve efficient integration of multiple electronic platforms and alleviate the shortage of wireless channel electronic spectrum,a structure and algorithm for airspace multi-beam radar-communications integration combining time-modulation array(TMA)technology and multi-beamforming technology is proposed.The traditional integration technology of space division-based radar-communications integration technology has been improved.While increasing the communications beam,the independent control of the transmission power of the radar and the communications subsystem has been achieved.The proposed structure consists of two sets of weighted networks.The first set of weighted networks is used for radar detection,and the second set of weighted networks combined with periodic time modulation is used for multi-user communications.According to the actual application,the proposed solution can be weighed among multiple indicators such as the number of users,the degree of freedom of beam control,and the complexity of hardware.The simulation results verify the effectiveness of the proposed structure and algorithm.Radar and communications can independently perform their functions without mutual influence.
