  • Description:
    This thesis is the result of research into new concepts of remote sensing of the atmosphere and includes a literature survey of the theory and practical application of atmospheric sounding using acoustic methods. The "state of the art" has been advanced in that a new type of system was designed, fabricated, and tested using modern digital methods. The major advances of replacing the typically troublesome facsimile recorder with a dot-matrix line printer using special characters called "tonels" and the development of a new and novel method of digital Doppler signal processing using a real covariance technique, is presented in detail.

    The echosonde is capable of monitoring and displaying in real time the temperature fluctuations, turbulent velocity inhomogeneities, and vertical wind profile of the planetary boundary layer to a height of 680 meters and includes a microcomputer, a high-speed line printer, and various author-designed and -constructed digital and analog circuits.

    User control of various system parameters and a wide choice of display possibilities make this a versatile and desirable atmospheric research tool.
