Car tire noise transmission path and signal attenuation modeling analysis: from data simulation perspective

Car tire noise transmission path and signal attenuation modeling analysis from data simulation perspective is conducted in this paper. Noise is accurately and quantitatively estimated, so actual measurement has become an important method for studying tire noise characteristics. In this study, the focus will be on the signal processing. This paper uses the various excellent characteristics of optical fiber channel to transmit the original analog echo signal of the radar remotely, so as to install the intermediate frequency sampling extension, general signal processing extension. With the integration of the complex and efficient signal collection and processing, the proposed model is applied to the noise detection scenarios. The simulation is conducted under different types of tires and the comparison analysis of the noise detection performance is considered.
