摘要：
This article describes a measurement setup for non-contact, spatially resolved temperature measurement of gases. The electromagnetic-acoustic interaction, known from the radio-acoustic-sounding method, makes it possible to measure temperatures continuously in the industrial environment. For this purpose, the speed of sound of an emitted sound pulse, which is temperature-dependent, will be determined with a Doppler radar. The operating principle, a possible setup and its challenges are shown and presented with measurements. Further, it is discussed how air flows or temperatures can be determined multidimensionally with this measuring principle.
