摘　　要：介绍了基于多相滤波的数字信道化接收机及其实现方法,讨论了跨信道信号、"兔耳效应"和重复信号等虚假信号的场景。针对每一种虚假信号,都进行了相应的仿真,给出了详细的说明。在介绍三种虚假信号特征的基础上,提出了消除虚假信号的方法,并提供了完整的处理流程。最后,通过MATLAB仿真结果验证了方法的有效性。At first, the digital channelization receiver based on the polyphase filter and its realization are introduced briefly. Then the scenes of false signals such as cross channel＂rabbit ear effect＂and duplicate signals are discussed. For every false signal,the detailed explanation is provided after simulation. Based on the features of the three false signals, the methods of false signals elimination are proposed. The integrated process flow is also offered. At last, the availability of the methods is proved through the result of MATLAB simulations.
