Abstract :
In this paper, a scheme of a subpicosecond dispersion range-finder is proposed and an estimate of the precision of range-finding for large distances in open atmosphere using this device is performed. Using subpicosecond pulses allows us not only to improve range-finding precision, but also to eliminate the effect of air refractive index indeterminacy on the path of propagation quite effectively.
