摘要：
A wideband calorimeter intended for measuring energies of the pulsed microwave radiation with duration of several nanoseconds to 1 s is described. The calorimeter’s principle of operation is based on measuring the volume increment that results from heating, when the radiation is absorbed by a polar liquid. The energy measurement range is 10 mJ–100 J, the energy-absorption coefficient is >0.9 in a frequency band of 1.6–20 GHz and ∼0.99 at frequencies of 4–18 GHz. The measurement error of the absorbed energy in the range 0.2–50 J does not exceed ±4%.
