Abstract
The theory of a non-coherent spread spectrum ranging system is introduced. The influence of cy―clic skipping on ranging precision is analyzed and a data processing method is presented. The double pseu―do noise ( PN ) clock sampling method with 180 ° phase difference is used to perform sampling and time difference comparison for two PN count numbers and two PN phases. Then the skipping values can be dis―tinguished and corrected,and the cyclic skipping of PN count number value can be removed effectively,so that the system ranging precision is ensured. This method has been successfully applied in many projects and the ranging precision meets the technical specifications.关键词
