    We report development on submillimeter wavelength detection system based on ac-biased superconducting antennacoupled transition-edge microbolometer operated at 4 K. The sensor is read out by low noise superconducting quantum interference device (SQUID) followed by room temperature ac electronics. Based on dc measurements, the should be below room temperature photon noise. Multiplexed readout enables construction of multi-pixel arrays with capability to sense subkelvin temperature differences at video frequency.
