Abstract
The invention relates to an electro-optical distance measuring method wherein frequency-modulated optical radiation is emitted onto at least one target to be measured. Once the radiation back-scattered to the target is received, the chirp of radiation is modeled by means of a phase function Φ(t) having parameters cj, thereby making description of the deviation of the chirp from the linear profile possible. The parameters used for description are at least partially determined from measurements or are coestimated during numerical signal processing.
