A scheme to obtain relatively scaled profiles of electron cyclotron emission (ECE) temperature directly from uncalibrated raw radiometer data is proposed and has been tested for the 2009 campaign KSTAR plasmas. The proposed method utilizes a position controlled system to move the plasma adiabatically and compares ECE radiometer channels at the same relative radial positions assuming the profile consistency during the adiabatic change. This scaling method is an alternative solution when an absolute calibration is unreliable or too time consuming. The application to the two dimensional ECE imaging data, wherein calibration is extremely difficult, may also prove to be useful.
提出了一种直接从未经校准的原始辐射计数据中获取电子回旋辐射（ECE）温度相对标度剖面的方案，并已针对2009年KSTAR等离子体实验进行了测试。所提出的方法利用位置控制系统使等离子体进行绝热移动，并在绝热变化期间假设剖面一致性的情况下，比较相同相对径向位置处的ECE辐射计通道。当绝对校准不可靠或过于耗时的时候，这种标度方法是一种替代解决方案。该方法应用于二维ECE成像数据（校准极其困难）时可能也会很有用。
