An advanced tool of the CNR IMAA EO facilities: Overview of the TASI-600 hyperspectral thermal spectrometer

The paper shows the TASI-600 thermal hyperspectral sensor acquired by the Italian National Research Council Institute of Methodologies for Environmental Analysis (CNR-IMAA) and describes some of the checks carried out during the commissioning phase. Furthermore, the first data acquired during the test-flight on hot spots of the volcanic island of Ischia (Central Italy) are shown. TASI-600 sensor has 32 spectral bands in the 8.0-11.5 mm spectral range, with a swath of 300 pixels and an IFOV of 1.2 mRad. The paper gives an overview of the principal TASI-600 characteristics, the CNR IMAA performance requirements and an overview of the technical innovation. Some of the outcomes of the tests performed in our laboratory in the Final Acceptance Test were focused to verify the linearity of the sensor up to higher temperatures (i.e. up to 500 K). Preliminary analysis of the in-flight and lab functional tests demonstrated that TASI-600 meets CNR IMAA requirements and as regard the radiometric accuracy it results higher than the requested.
