In this paper, the dynamic data acquisition and processing methods in the inlet experiment are introduced. The influences of the filter cut-off frequency and the different flow in the inlet on the dynamic distortion index are studied. The data obtained in the interference state are analyzed by traditional methods, statistical methods, Methods were analyzed and processed, and the resulting real-time data were spectrum analyzed.
