Paper Abstract

Performance of CO2 doppler lidar for fixed hard target at low laser frequency stability is presented using the novel wide-band doppler detection technique described before. The approximate maximum likelihood estimator is used. The velocity estimation error is experimentally determined at various SNRs and is compared to the Cramer-Rao Bound. Our results show a deviation of the unbiased velocity error from the CRB less then the width of the confidence interval for the error. The biasing of the estimator at low SNRs is studied experimentally for non-ideal equipment performance; we propose the Gaussian model of the distribution of so called 'bad' estimates are more appropriate for experimental data, instead of the uniform one recommended.
