超导亚毫米波临边发射探测器已成功开始在轨运行。本文介绍了地面试验和在轨性能测量的结果，并进行了比较。结果表明，SMILES卫星的在轨性能完全满足指标要求，其数据质量足以满足大气科学研究的需要。如果对地面测试结果进行正确修正，在轨系统噪声温度与地面测试结果是一致的。所测量的系统噪声温度测量也受到接收器增益非线性的影响。在SMILES的1B级处理中仍有改进的余地，例如非线性校正，
Superconducting Submillimeter-Wave Limb- Emission Sounder (SMILES) has successfully started in-orbit operation. The results of the ground tests and in-orbit performance measurements are described and compared in this paper. We found that the in-orbit performance is fully satisfy the specifications and SMILES data has sufficient quality for atmospheric science study. The system noise temperature in orbit is consistent with that measured in the ground test if the result of the ground test is modified correctly. The measured system noise temperature measurement is also influenced by the receiver gain nonlinearity. There is still a room for improvements, for example nonlinearity correction, in Level 1B processing of SMILES,
