The Research on the Realization of Isochronisms Sampling Using Digitalized Phase-locked

摘要

The isochronisms sampling is an elementary problem in the test field. This paper introduces a digitalized method for isochronisms sampling and how to use it to set up system. The traditional method to solving isochronisms sampling is put forward firstly. In the analysis, this method has many disadvantages such as the precision of isochronisms sampling is low and the hardware design is complex. Compared to this tradition method, the digitalized phase-locked scheme adopts the technology of digitalized phase-locked which simplified the design of system hardware greatly; at the same time the precision of system isochronisms sampling is enhanced greatly. This method has a good future and has been used in the field of infrared-target identification successfully.
