A new lidar scheme using a pseudorandom code modulated cw laser as a transmitting laser source (RM-CW lidar) is proposed and a demonstration of its use for aerosol measurement is shown. A formula for estimating the SNR values in RM-CW lidar was derived, and it was demonstrated that the observed SNR value was in good agreement with the calculation.

  11. In the case of photon counting, a theory (Ref. 10) gives the counting efficiency in the form ζ=[1−exp(n¯Δt)]/n¯Δt, where n¯ is the average count of incident photons/sec and Δt is the unit gate time. The error limit of 10% in ζ corresponds to n¯Δt being 0.2, which gives n¯ to be 106 photons/sec for Δt = 200 nsec. This situation was attained by raising the discrimination level.
