This paper presents some details pertaining to phase based range refinement algorithms for accurate range refinement of Light Detection And Ranging (LADAR) instruments. The challenges associated with wave form identification and peak-to-peak distance quantification are outlined and associated algorithms to establish peak to peak correlation between the sent and return wave forms of light are summarized. Using digital phase modulation methods, it is anticipated that some of the challenges associated with pulse digitization in LADAR range refinement algorithms can be overcome. Barker 7 and 13 codes are shown to capture the phase delay in the pulses. Implementation issues that drive the utilization of the wave form processing ideas are discussed in the context of the novel HD6D LADAR system developed by the authors.
