The meteor head echo observation using the MU radar (46.5 MHz, I MW), Shigaraki,Japan has been developed since 1998 for Leonid meteor observations. Orbits of faint meteorswith +15 magnitude can be measured with a precision of 0.5 degree (Nishimura et al., 2001).Simultaneous optical observation with an ICCD (Image-intensifled CCD) video camera was carriedout. Instantaneous radar signal intensity and video magnitudes are closely compared by using atime-recording system synchronized to GPS signals. We have found that the light curve and timevariation of radar signal intensity compares fairly well in many cases, but quite frequently the radarsignal becomes decreased by 10-20 dB quickly without any significant change of video magnitude.This suggests a change of radar scattering mechanism of a meteor head during the flight. |
