Radar reflections from explosion and gas wake of operating engines

The mechanisms of radar reflections from the explosion area and gas wake of operating engines are analyzed; it is shown that the reflections caused by radiowave backscattering from a turbulent gas-like explosion and combustion products can be observed for rather a long time. The results of the investigations into local spatial-temporal characteristics of the disturbed area and radar observations, carried out at wavelengths 10, 3, 0.8, and 0.4 cm are presented.
