Abstract:
|
A methodology aimed at validating elastic-channel optical
power return and signal-to-noise ratio (SNR) levels
estimated at the link-budget design stage of a tropospheric
lidar against the measured ones is presented. A Rayleigh fit
along with knowledge of the atmospheric aerosol
transmittance and emission energy is used to theoretically
estimate the net voltage responsivity. As a further
refinement, when simultaneous analog and photon-counting
acquisition is available, the method formulates a rough
estimate of the optical losses in the receiving chain.
Preliminary validation of the link-budget-assessed optical
power and SNR levels for the 1064-nm channel of the Remote Sensing Lab. (RSLab) lidar is discussed. |
