Capabilities of Radio Interferometric Observations in the 750–1200 GHz Bands

This paper analyzes the feasibility of using the 750 and 1200 GHz frequency bands in radio interferometric observations. It examines current scientific challenges that can be addressed in these bands, as well as limitations related to atmospheric transparency, receiver sensitivity, and coherent signal integration. Taking these limitations into account, the potential for using these bands for various observational instruments is explored. Based on the assessments, it is proposed to consider the 750 and 1200 GHz frequency bands as part of a compact antenna array concept on the lunar surface as the most feasible and optimal solution for implementing high-frequency radio interferometry. Calculation key parameters are presented, defining the basic constraints and requirements for such a system.
