Abstract :
In this paper, the detection problem of complex LFM (linear frequency modulation) signal based on cyclic autocorrelation in multipath is discussed. The cyclic statistics of complex LFM is analyzed, and the detector based on the cyclic autocorrelation amplitude is constructed. Then, the detector properties are analyzed and output SNR of the detector is deduced. Finally, the performance of the detector is given through computer simulation, which is in agreement with the analytic results
