Beschreibung
Zusammenfassung:	Various embodiments may include a method for monitoring a hot gas region of a gas turbine comprising: monitoring the region using an imaging radar assembly remote from the region, connected to the region with a hollow conductor. The hollow conductor is closed off at a first end proximate the radar assembly. The radar assembly operates outside the closed-off cavity and the second end opens into the region or is shielded against heat but permeable to radar waves passing into the region. The radar is actuated in time intervals wherein at least parts of the hot gas space are detected by the radar assembly repeatedly at the time intervals. The method includes: feeding acquired image data to an evaluation device; evaluating the acquired image data against a predefined maintenance requirement; and triggering a maintenance alarm as a function of the result of the evaluation.
