 note = {We have investigated the detection capability of the seismometer on board the penetrator for moonquake events. The noise level of the penetrator seismometer system was compared not only with the amplitudes of moonquake events in time domain, but also with their Power Spectral Densities (PSD) in frequency domain. In the investigation, the characteristics (resonant frequency and damping constant) of two components of seismometers system (sensors, gimbals mechanism and measurement electronics) on board the penetrator after a penetration were used to represent its frequency response. Their values were converted to those at -20 C predicted on the Moon in consideration for temperature dependence of sensor characteristic. The results of the investigation showed that the seismometer system on board the penetrator could detect deep moonquake events which have small amplitudes (about one-two digits) identified by the Apollo seismic observation on the moon., 資料番号: AA0063723012},
