Abstract
A method is disclosed for improving performance of a Sodar system adapted to locate discontinuities in the atmosphere by transmitting pulse compression signals such as plural acoustic chirps. The method comprises transmitting the acoustic chirps, receiving acoustic echoes of the chirps, and processing the acoustic echoes to provide an indication of the discontinuities, wherein the processing includes correcting range or resolution error associated with the acoustic echoes.

A method of improving performance of a Sodar system adapted to locate discontinuities in the atmosphere by transmitting pulse compression signals such as plural acoustic chirps, said method comprising:
- transmitting the acoustic chirps;
- receiving acoustic echoes of the chirps;
- and
- processing the acoustic echoes to provide an indication of said discontinuities;
- wherein said processing includes correcting range error associated with the acoustic echoes, and wherein the step of correcting range error is performed at each of a plurality of range segments and including adding together outputs of the corrected range segments to provide a corrected range profile.

- transmitting the acoustic chirps;
- receiving acoustic echoes of the chirps;
- and
- processing the acoustic echoes to provide an indication of said discontinuities;
- wherein said processing includes correcting resolution error associated with the acoustic echoes.
A method of improving performance of a Sodar system adapted to locate discontinuities in the atmosphere by transmitting pulse compression signals such as plural acoustic chirps, said method including:
- transmitting said acoustic chirps in plural frequency segments;
- receiving echoes of said acoustic chirps in plural frequency segments;
- processing each frequency segment to provide an output for each segment;
- and
- summing said outputs of said frequency segments to provide an indication of said discontinuities.
