STUDY DIRECTED TOWARD OPTIMIZATION OF OPERATING PARAMETERS OF THE EMAC PROBE FOR THE REMOTE MEASUREMENT OF ATMOSPHERIC PARAMETERS

摘要

The concept of utilizing sound waves as reflectors for pulsed Doppler radar as a means for measuring wind velocity, turbulence, and air temperature has been examined theoretically. Any extension of the initial and successful, small scale experiments performed by Midwest Research Institute to a practical system for atmospheric probing is shown to require a change in the operating concept of the acoustic system. This change involves the abandoning of the concept of coherent reflection reinforcement from a multiple wave train and the substitution of reflection from a single acoustic shock front with the introduction of coherent integration of the pulsed Doppler radar signal.
