This paper considers characteristics of a resonance bolometer which is an infrared radiation detector depending for its operation on measuring the temperature dependence of parameters of a reactive element connected into a high-Q oscillatory circuit. The optimal pumping and heat removal conditions are determined with consideration for thermal feedback. The voltage-power sensitivity and noise are measured for microwave-pumped bolometers with active elements (cryogenic dielectric resonators made of potassium tantalate and strontium titanate) included in their circuits.
