摘　　要：针对传统侦察干扰机实现收发同时和多信号同时干扰时耗费硬件资源,工程实现较难的问题,设计了一种基于信道化的雷达侦察干扰系统。该系统利用正交镜像滤波器组,实现雷达信号的信道化接收和精确重构,同时基于DRFM技术实现多种信道化干扰方式。仿真结果表明,该设计的基于信道化的雷达侦察干系统设计方案具有很小的信号重构误差,可以实现信号的精确重构,完成多种信道化干扰,同时具有收发同时和多信号同时干扰的能力。When simultaneous transmiting and receiving and multi-signal,more hardware resources are consumed in the traditional reconnaissance jamming machine,the engineering realization is difficult too,a channel-based radar reconnaissance interference system is designed.A quadrature mirror filter bank is utilized in this system to realize channelized reception and accurate reconstruction of radar signals,and multiple channelization interference modes are implemented based on DRFM technology.The simulation results show that the channel-based radar reconnaissance system design scheme has less signal reconstruction errors,which can realize accurate signal reconstruction,complete multiple channelization interferences,and with the ablity of simultaneous transmiting and receiving and multiple signals simultaneous interference.
