Other AbstractMedium Frequency(MF)radars can be used to develop the meteor observations over 100 km during night time,and detect the distributions of hourly echo rate,height and angle of arrival.The meteor entrance speeds,meteor radiants and radial drifted velocities can also be determined.These data can be used to study meteor astronomy and middle atmosphere dynamics.The meteor observations in middle latitudes for the first time in China are developed by using of Langfang MF radar(39.4°N,116.7°E)during 12:00UT-22:00UT on November 16,2017.The receiving range of the echoes was set from 78 km to 150 km.The time and height resolutions are 2min and 2 km respectively,and the pulse repetition frequency is 80Hz.As a result,totally 94 meteor echoes were obtained with the mean height of 106.5 km and the majority of them were distributed from 97 km to 115 km.Ambipolar diffusion coefficient,angle of arrival and some relevant parameters were simultaneously analyzed using the raw data.The results of the comparison between Buckland Park MF radar meteor observations and Langfang MF radar observations show that the detections of the two radar are mostly consistent.
