As the PN-code high performance of long period and the coherence, the very long distance and high precision ranging can be reached at the same time. Multi-target TT&C can be reached by CDMA of PN.
Various parameters insisting of spectrum of source, imaging distance and spatial coherence can influence visibility of fringes. Their referential values were presented in this paper.
