摘　　要：针对多相滤波信道化结构存在信号接收模糊的问题,把频域拼接法运用到信道化接收机中,给出了拼接法的实现过程框图和拼接步骤,解决了信号接收模糊问题。最后评估到达时间差对拼接质量影响,得出在拼接到达时间差小于100ns时,信号的质量较为理想。仿真表明,该方法具有有效性。A new method based on frequency domain is proposed to solve the blind frequency zone of polyphase filter. In view of the blind frequency zone, the realization of the process and the steps of the frequency domain method are given. Finally, the influence of the time difference of arrival on the splicing quality is evaluated, it is concluded that the signal quality is better when the difference of the time difference of the splicing is less than lOOns. And its validity is verified by the simulation with MATLAB.
