| 内容記述 | HRO (Ham Radio Observation) is one of the valuable methods of observing meteoractivity. However, it not only has the advantages but also suffers from unknown detective fieldof HRO. If the field would be transformed by zenithal position of radiation point, the numberof meteor by HRO is not reliable. Thus, the purpose of this report is to prove time shift of thedetective field through simulation. HRO is the meteor radar of a forward scatter systern. If thesurface of the meteor trail is smooth and enough size for frequency, this system can receive echoof the meteors under the following below-mentioned conditions.-The ionized-trail touches the spheroid, for which the transmitting station and the receiving stationare positioning on focus.-The height of ionized-trail is about 100km (average height of meteor trail) .The field on this condition was calculated by Microsoft Excel and plotted values of the results.Consequently, the area transition and time shift of the detective field were successfully simulated.And in the simulation it is shown that there exists the dead time among which HRO cannotreceive a specific meteor stream. Actually, the author could not receive echo of Geminids (Dec.12-16 1999) by using HRO at midnight. In conclusion, this study established one of the basicmethods to estimate the real number of meteors by HRO observation data. | |||||||||
