The Randomness of Sporadic Meteoroids in Radio Observations

We examine an uninterrupted set of radio observations of mostly sporadic meteoroids to determine whether these meteoroid events occur purely randomly in time or whether short burst of events may contribute. Event clustering on a short time scale of about a minute, but larger then one second, is examined in a background of statistically distributed events modulated with a diurnal dependence. We find that in the present data set all events can be attributed to chance coincidences. It is also shown that if some occasional clustering does occur, this can not be identified by statistical means based on event timing only, thus requiring additional observables.
