Interpreting experimental diagnostics data in tokamaks, while considering non-ideal effects, is challenging due to the complexity of plasmas. To address this challenge, a general synthetic diagnostics (GSD) platform has been established that facilitates microwave imaging reflectometry and electron cyclotron emission imaging. This platform utilizes plasma profiles as input and incorporates the finite-difference time domain, ray tracing and the radiative transfer equation to calculate the propagation of plasma spontaneous radiation and the external electromagnetic field in plasmas. Benchmark tests for classical cases have been conducted to verify the accuracy of every core module in the GSD platform. Finally, 2D imaging of a typical electron temperature distribution is reproduced by this platform and the results are consistent with the given real experimental data. This platform also has the potential to be extended to 3D electromagnetic field simulations and other microwave diagnostics such as cross-polarization scattering.

用于托卡马克微波成像诊断的综合诊断平台

由于等离子体的复杂性，在考虑非理想效应的同时解释托卡马克中的实验诊断数据具有挑战性。为了应对这一挑战，建立了通用合成诊断（GSD）平台，以促进微波成像反射计和电子回旋发射成像。该平台利用等离子体剖面作为输入，结合时域有限差分、射线追迹和辐射传输方程来计算等离子体自发辐射的传播和等离子体中的外部电磁场。通过经典案例的基准测试，验证GSD平台各核心模块的准确性。最后，该平台再现了典型电子温度分布的二维成像，结果与给定的真实实验数据一致。该平台还有可能扩展到 3D 电磁场模拟和其他微波诊断，例如交叉极化散射。
