A New Laser Ranging System Based on DDS Technology
Hanjun Luo · Modern Electronic Technique · 2005
This paper advances the whole design scheme of consecutive wave phasic laser ranging,based on Direct Digital Synthesis(DDS),and describes the characteristics and principles of DDS and phasic Laser Ranging,and gives some basic analysis about the spuriousness characteristics of DDS.In the system,high stable frequency and low phase DDS are used,they can realize high accuracy and the performance of the system will be enhanced more.
