HIRDLS仪器与任何其他遥感器一样，必须能够在其使命寿命期间保持高度的测量精度。影响辐射稳定性的因素很多，包括直接和间接的热效应以及其他老化过程。理想情况下，传感器应该能够“自我校准”，并且必须有独立的方法来跟踪其长期精度。对于HIRDLS仪器来说，由于“自校准”方面的缺陷，地面数据处理器可获得的高保真数据提供了实质性证据，证明它保持了良好的长期“精度”。详细的长期性能的介绍和讨论，连同参考的一些问题及其解决方案。
The HIRDLS instrument, like any other remote sensor must be able to maintain a high degree of measurement accuracy through its mission life. There are many factors that influence radiometric stability including direct and indirect thermal effects and other aging processes. Ideally the sensor should be capable of 'self-calibrating' and there must be independent methods to track its long term accuracy. For the HIRDLS instrument, being handicapped with regard to 'self-calibration', the high fidelity data available to the ground data processors provide substantive evidence that it has retained good long term 'accuracy'. Details of the long term performance are presented and discussed, together with reference to some problems and their solutions.
