Time-frequency analysis technique is an effective analysis tool for non-stationary processes. In the fieldof reactor neutron noise, the time-frequency analysis method has not been thoroughly researched andwidely used. This work has studied the time-frequency analysis of the reactor neutron noise experimentalsignals under bubble disturbance and control rod vibration. First, an experimental platform wasestablished, and it could be employed to reactor neutron noise experiment and data acquisition. Secondly,two types of reactor neutron noise experiments were performed, and valid experimental data wasobtained. Finally, time-frequency analysis was conducted on the experimental data, and effective analysisresults were obtained in the low-frequency part. Through this work, it can be concluded that the timefrequencyanalysis technique can effectively investigate the core dynamics behavior and deepen theidentification of the unstable core process
