Abstract: Terahertz radiation characteristics of blackbody are theoretic basic of detecting terahertz radiation, and also the key of how to calibrate and measure terahertz sources. Terahertz radiation characteristics of blackbody are analyzed, and terahertz bolometer radiometer is built, then the terahertz radiance of blackbody, which temperature range is (223～323) K, are tested by bolometer radiometer. Furthermore, the radiance of folded waveguide traveling-wave tube is tested. The results show that the method which can test terahertz radiation parameter of terahertz source is provided.
Keywords: Terahertz source measurement, Radiation blackbody, Terahertz bolometer radiometer.
