Piece-wise variance method for signal-to-noise ratio estimation in elastic/Raman lidar signals
Document typeConference report
Rights accessOpen Access
A straightforward signal-to-noise ratio (SNR) estimator for elastic/Raman lidar channels and related noise-induced errorbars is presented. The estimator is based on piece-wise estimation of the mean signal power and noise variance component under analog detection. The piece-wise estimator results are compared with those obtained from a previously published SNR parametric estimator under high and low SNR scenarios.
