| Abstract: | The implementation of the "Sun-Terahertz" space experiment is scheduled for 2026–2029 aboard the Russian segment of the International Space Station. The objectives of the experiment include acquiring data on the terahertz radiation of the Sun, as well as studying solar active regions and solar flares. The scientific equipment of the "Sun-Terahertz" experiment comprises eight detectors with the target frequencies ranging from 0.4 to 12.0 THz. The expected spectral characteristics of the scientific equipment are presented, and a method for their experimental verification using an additional low-pass filter is briefly described. The necessity of enhancing the frequency selectivity of the detectors is emphasized, and two methods for achieving such enhancement are considered. To assess the sensitivity of the detectors, an experiment was conducted to measure solar radiation using a single-channel prototype, which is a full-scale analogue of one of the detectors of the scientific equipment with the ability to replace bandpass terahertz filters. A two-axis rotary platform and a cloud sensor were developed for the single-channel prototype. Based on the results of the experimental verification, conclusions were made about the sufficient sensitivity of the detectors of the scientific equipment to isolate the solar signal against the intrinsic noise background, as well as the potential for improving performance in terms of frequency selectivity. In this context, it is feasible to use a method of linear combinations of detector signals. The obtained results will be of value for those experimenting with spectrometric scientific instruments based on optoacoustic transducers (Golay cells) and other sensitive elements.
