摘　　要：研究了基于循环相关的多径线性调频信号检测问题,分析了检测器中循环相关延迟与检测统计量的关系,给出了一种改进的多径线性调频信号循环相关检测器,并对其检测性能进行了分析。仿真结果验证了理论分析的正确性和实用性。The detection problem of the multipath linear frequency-modulated(LFM) signal based on the cyclic correlation is discussed,and the relation of the cyclic correlation lag with the detection statistics of the detector is analyzed.Then a revised cyclostationary detector for the multipath LFM signal is constructed,and the multiapth signal is detected.And the detector properties are analyzed and the output SNR of the detector is deduced.Simulation results prove that the theoretical analyses are correct and pract...
