Abstract
The possibilities of radar observation of effects occurring during aerodynamic object flights with sonic and supersonic speeds are considered. Three mechanisms resulting in electromagnetic wave backscattering are analyzed: reflections from shock wave taking place for atmosphere object flight with supersonic speed, reflections from sonic field leading to atmosphere parameter modulation, and scattering from atmosphere turbulence and parameters of which are varied by sonic field influence. The results of experimental study of sonic interaction with atmosphere turbulence are presented. It is shown that the most perspective mechanisms for radar observation are the first and the third ones, the directions of further investigations are put forward.
