A digital acoustic echo sounder and display system with Doppler wind and turbulence estimation
Abstract
A digital acoustic echo sounder with Doppler wind and turbulence estimation capability is described. The system, which uses 2 KHz for atmospheric sampling, is adjustable in range increments of 170 m and can be fine tuned with transmitted pulse width, receiver blanking adjustments, and system gain. Dot matrix printer technology was used for the display, which is controlled by a DEC LSI-11 microcomputer. Wind speed and direction, sigma values, and meander parameters can be obtained from heights near the surface to more than 600 m from monostatic and bistatic sampling of the Doppler frequency shift. These are displayed at the appropriate height on the atmospheric temperature structure display. Data can be stored on standard magnetic tape or discs
