Paper presents the review of experimental data on the measurements of radiative characteristics of shock waves as well as comparison of measurements of nonequilibrium spectral radiation of shock-heated N2-O2 and CO2-N2 gas mixtures with the results of numerical simulations. The experimental results on the absolute measurements of nonequilibrium spectral radiation were obtained on the shock tubes of Laboratory of Kinetic Process in Gases of Institute of Mechanics MSU. The numerical nonequilibrium spectral features of the shock-heated gases in absolute units were obtained using the model of nonequilibrium radiation emitted in the relaxation zone.
