| 摘 要： | 本文描述了8mm波段超外差前馈跟踪系统的原理及在聚变等离子体实验装置上的应用。它适用于在强的辐射条件下的微波干涉、微波散射及微波传输等实验。具有很高的抑制辐射噪声干扰的能力。本文详细介绍了此系统小型磁镜实验装置MM-2中等离子体密度的测量方法,它有效地克服了由于该装置中由同步辐射造成的强的干扰,信噪比大于45分贝。该系统优于其他诊断系统的特点在本文中也进行了讨论。

| Abstract: | The principle of a microwave Superhete-rodyne feedforward tracking system and its application on fusion plasma devices are discribed in this paper. This system can be used to observe scattering, interferometry and trarsport signal of microwave in the presence of strongradiation noise. A 8 mm microwave superheterodyne feedforward tracking system has been used to measure the Plasma density in a small magneticmirror device MM-2 and the disturbance of synchrotron radiation has been overcome effectually, The signal-noise ratio of the system is larger than 45db. It's characteristics preferable to other diagnostic systems are also discussed. |
