This article describes full-scale tests of a prototype of a IR Fourier spectral-radiometer for remote atmospheric sounding. The article presents an experimental procedure, which would allow one to determine the efficiency of the device and its metrological characteristics. Additionally, the article presents results of tests with the use of test objects such as films made of different polymer compounds (polyester, Teflon, polyethylene, polystyrene) with known thickness, as well as vapor of ammonia (NH3) and sulfur hexafluoride (SF6) in gaseous phase. The spectra of test objects were registered against various background objects - a clear sky, a cloudy sky, a model of a black body with a known temperature.
