Abstract :
This paper describes 100-MHz measurements of the amplitude-probability (APD) and crossing-rate distributions (CRD) for automotive-traffic radio noise at Toyokawa, Japan. Two different categories of the results of measurements for automotive-traffic radio noise are described: 1) one category is the aggregate of APD/CRD pairs measured for the noise samples of 15-min duration, each of which gives a statistically stationary datum, and 2) the other is the aggregate of APD/CRD pairs measured for the noise samples of 2-s duration, each of which gives a transient datum belonging to the components of a statistically stationary datum. A series of the noise grades for single-motor vehicles passing on a motorway is described in terms of APD/CRD pairs for the noise samples of 2-s duration.
