Abstract

We developed an analytic framework to asses the performance of wind velocity measurements with the edge technique using a pulsed lidar. This technique is insensitive to frequency jitter and shifts of both laser and filter. This paper analyzes the applicability of the edge technique for a pulsed lidar. We show the velocity estimation with the edge technique is, in general, biased and that the bias depends on signal fading statistics, energy/pulse, and the number of pulses used for estimation. Two practical signal processing algorithms are considered for the wind velocity estimation. Analysis of their performance includes the trade-off between the number of pulses and energy/pulse. The effect of partial coherence of laser radiation is bounded by considering two limiting cases: (1) signal fading and its coherence can be neglected; and (2) signal fading is very strong and the effects of coherence degrade the lidar performance.
