| 内容記述 | Synchronous analysis of the four statistical parameters has been realized by the introduction of a digital computor system specially designed for the measurement of atmospheric radio noise measurement of a given short duration. The four statistical parameters are the parameters that give both the amplitude characteristics of the radio noise and the time characteristics on the time sequence of the radio noise intensity, namely they are amplitude probability distribution, crossing rate distribution, probability distribution of duration of pulses, and probability distribution of the occurrence time interval between pulses. In this paper are described the system that measures the atmospheric radio noise and the system that processes the digital data including the process of conversion from analogue to digital. The four statistical parameters have been analyzed with the aid of a new data processing system that can be applied to the atmospheric radio noise measurement. Synchronous analysis of the four parameters is expected to lead to a precise investigation on the close corelation between them. In this paper the suggestions being made on these points are that: The shape of the amplitude probability distribution can theoretically be determined from the shape of the corresponding crossing rate distribution. A particular curve of the crossing rate distribution is shown on a graph, because the corresponding amplitude probability distribution follows a log normal law. A data is shown, which shows a possible transformation between the probability on A. P. D. and the crossings per second on C. R. D.. The probability distributions of duration of pulses and those of the occurrence time interval between pulses are shown as a function of threshold values that cover 80 dB dynamic range of amplitude variations, where surprisingly good resemblance can be found between probability distributions of the occurrence time interval between pulses in day times, and those in night times. | |||||
