为了实现对联合战术信息分发系统( JTIDS)信号的宽带接收，设计了一种基于多相滤波器的信道化接收方法。该方法通过对JTIDS的模拟信道和数字信道进行合理划分，将宽带接收转化为多个窄带接收，然后再结合多相滤波器进行跳频频点检测，以实现全概率的JTIDS信号宽带接收。给出了此信道化接收模型的现场可编程门阵列( FPGA)实现方案，并对仿真和硬件测试结果进行对比分析。仿真与FPGA测试结果表明，该接收模型可以精确实时地接收JTIDS宽带信号。

In order to realize the Joint Tactical Information Distribution System( JTIDS) broadband signal reception,a method of channelized receiver based on polyphase filter is presented. Through reasonable di-vision of JTIDS analog channel and digital channel,the broadband receiver is converted into a plurality of narrowband receiver,and then combined with the polyphase filter for frequency hopping point detection to realize the full probability receiving JTIDS signal. The Field Programmable Gate Array( FPGA) implemen-tation scheme of channelized receiver model is provided,and the simulation and hardware test results are compared and analyzed. Simulation and FPGA test results show that the model can accurately receive JTIDS signals in real time.
