摘要：
The velocity of a supersonic gas flow has been measured using a modified method based on the cross-correlation analysis of signals from laser refraction sensors. The results of experiments showed that, for a cold flow (T0 = 297 K), the proposed method gives the flow velocity and temperature values close to those obtained using conventional gasdynamic measurements. The velocity of a preliminarily heated gas flow has been determined in the range of 500–750 m/s.
