    Area of Science:

    • Atmospheric optics
    • Laser remote sensing

    Background:

    • Laser Doppler wind sensing relies on aerosol scattering.
    • Signal statistics are typically modeled using complex Gaussian distributions for long ranges.

    Purpose of the Study:

    • To investigate the operational characteristics of a 1.55 µm continuous-wave (cw) laser Doppler wind sensor.
    • To analyze how signal statistics change with range and atmospheric conditions.
    • To assess the potential of single-particle detection for enhancing sensor performance.

    Main Methods:

    • Operation of a cw laser Doppler wind sensor at 1.55 µm.
    • Analysis of wind-signal statistics at varying ranges (from <8 m to >100 m).
    • Examination of different atmospheric backscatter conditions.

    Main Results:

    • At ranges >100 m, signals follow complex Gaussian statistics.
    • At ranges <8 m, signals are dominated by single-particle events with high signal-to-noise ratio (SNR).
    • Single-particle scattering influences results up to ~50 m, deviating from Gaussian statistics.

    Conclusions:

    • The performance of laser Doppler wind sensors is range-dependent.
    • Single-particle detection offers significant SNR enhancement, particularly at shorter ranges.
    • Exploiting single-particle events can lead to improved low-power wind sensor designs.
