Abstract

A new laser range finding method using direct sequence spreads spectrum (DSSS) and phase-shift keying (PSK) modulation is described in this paper. Comparing with pulse, phase-shift and other normal methods, it provides more benefits such as improving receiver sensitivity and avoiding range ambiguity, due to the property of long periodic pseudo noise (PN) sequence. The operation theory and simulation result are also introduced.
