摘要：
The optimal kernel distribution of Cohen class time-frequency distribution (TFD) was analyzed, a method of time-frequency correlation based on Cohen-Reassignment TFD was proposed. The analysis method could depict frequency-hopping signal efficiently and has higher resolution on time-frequency domain, and could reduce or completely remove the cross-terms and diffuse other signal components. The computation could adopt module algorithm with lower computation complexity, so it could be used for rapid tracking and acquisition of frequency-hopping communication systems. The computer simulation was also presented to show the performance of the analysis method.
