Cyclic correlation detection method applied to weak LFM signals in multiplicative noise
Chunlin Huang, Yiyu Zhou · 2005
In this paper, the cyclic-correlation detection method is proposed to detect the LFM signal. Despite the fact that the multiplicative noise is presented, this method has a high processing gain. The expressions of output SNR are derived which are identical with the simulation results. It is concluded that the cyclic-correlation method is proper for the detection of the weak signal in the complicated background that includes the multiplicative and additive noises.
