Laser Doppler and Phase Doppler Signal ProcessingLaser Doppler Data Processing
  
  
The laser Doppler and phase Doppler signal processing includes
  • the analysis of the equally sampled Doppler burst
  • the signal detection
  • the derivation of the particle velocity
  • the derivation of the particle acceleration
  • the derivation of the particle arrival time
  • the derivation of the particle transit time
  • the derivation of the signal phase (e.g. for phase Doppler)
  • the detection and characterisation of particle oscillations
  • the validation
The laser Doppler data processing includes

    • the velocity variance
    • the autocorrelation function
    • the correlation coefficient
    • the structure functions
    • the power spectral density
  • the derivation of characteristic flow parameters as
    • the integral time or length scale
