| Abstract: |
| In this paper, scheme of the double loop tracking system which is used to acquire and track a commpound PN code with a clock component in radio measurement and its control system of digital telemetry codes and image signal mixed transmission is put forward.Acquisitions performance of double loop system is analysed.Theory analyses and experiments have proved that double loop system using a three component code not only has short acquisition time but can resist the high power level interference. |
