PY 2012 BP 557 EP 568 VL 54 IS 8 DI 10.1007/s11141-012-9314-z DE Millimetron space observatory; HEB applications AB We present an overview of the state of the onboard receiving complex of the Millimetron space observatory in the development phase of its preliminary design. The basic parameters of the onboard equipment planned to create and required for astrophysical observations are considered. A review of coherent and incoherent detectors, which are central to each receiver of the observatory, is given. Their characteristics and limiting parameters feasible at the present level of technology are reported. ER
