Development of the portable instrument for teaching purpose to determine the trajectory and the mass of a meteor by radio waves.

我们正在研制一种便携式教学仪器，利用无线电波测定流星的轨迹。本文提出了一种利用前向散射流星无线电回波与GPS同步多站观测来确定流星参数的新方法。我们开发了一种新的系统，该系统通过流星轨迹测量从发射点到接收点的距离，以确定更详细的流星轨迹。该系统是使用与GPS同步的FMCW（调频连续波）无线电波以200ksps的分辨率接收数据的规范。我们成功地测量了从发射点通过流星轨迹到接收点的距离。

We are developing a portable instrument for teaching purpose to determine the trajectory of a meteor by radio waves. We present a new method to determine the parameters of the meteor using a forward scattering meteor radio echo observation with GPS-synchronized multiple receiving stations. We developed the new system which measures the distance to a receiving point through a meteor trail from a transmission point in order to decide a more detailed the trajectory of a meteor. The system is specification which takes in data with the resolution of 200ksps using the FMCW (Frequency Modulated Continuous Wave) radio waves synchronized with GPS. We succeeded in measuring the distance to a receiving point through a meteor trail from a transmission point.
