摘　　要：主要探讨信道化接收机对同时到达的两相邻频率信号的精准参测问题。针对接收机对同一子信道内的两路信号难以实现精确测频与测向的挑战,通过对接收信号进行双通道共轭与单通道共轭分析,推导两信号到达相位差与双通道共轭信号相位、载波频率差与单通道共轭信号相位的函数关系,实现信道化滤波器带宽分辨率范围内,两路信号的瞬时精准测频测向,并通过仿真分析,验证该理论的正确性。The accurate frequency and phase measurement for digital channelized reception of two adjacent frequency signals are described.Through the cross correlation and autocorrelation analysis of the two intercepted signals by two digital channelized receivers,the functional relationship between the arrival phase difference of signals and the phase of the cross correlation signal,the carrier frequency difference and the phase of the auto correlation signal are deduced respectively.The deduction is verified with the simulation.The accurate frequency and phase measurements of two signals is achieved within the channelized bandwidth resolution.
