摘　　要：现代军用平台有限空间内集成了大量射频收发天线系统,导致共址电磁自兼容问题严重,干扰对消技术是解决共址同频干扰问题的一种重要手段。高跳速、环境剧烈变化场合对对消系统的处理速度提高了更高要求。论文提出了一种基于复数域QRD-RLS算法的数字域快速对消算法,推导出了其高速脉动阵实现结构,并在Xilinx FPGA上研究了实现方法。仿真和实测结果表明,高速脉动实现结构实时处理时钟频率可达60 MHz,可有效实现干扰对消功能,具有良好的工程实现度。Modern military platforms integrate a large number of RF transceiver antenna systems in a limited space,resulting in serious problems of co-site electromagnetic self-compatibility,and interference cancellation technology is an important means to solve the problem of co-site co-frequency interference.High jumping speed and drastic changes in the environment increase the pro⁃cessing speed of the cancellation system.In this paper,a digital domain fast cancellation algorithm based on complex domain QRD-RLS algorithm is proposed,and its high-speed systolic array implementation structure is derived,and the implementation method is studied on Xilinx FPGAs.The simulation and measured results show that the real-time processing clock frequency of the high-speed systolic realization structure can reach 60 MHz,which can effectively realize the interference cancellation function and has a good engineering implementation.
