The experimental results on the absolute measurements of spectral radiation of air obtained on the double diaphragm shock tubes of Laboratory of Kinetic Process in Gases of Institute of Mechanics MSU. Experimentally investigated the radiative properties of nitric oxide in the spectral range 190-290 nm. Obtained the time dependence of the emission of molecular bands for NO shock wave velocities of 4-10 km/s. Discusses the problems of absolute power measurement in the radiation behind shock wave front. The nonequilibrium UV radiations from shock-heated air are modeled with hybrid radiative-collisional model and then compared with experimental data.
