Abstract: |
Some goals are pursued by the unified Tracking, Telemetry and Command (TT&C) system in the future, which include higher accuracy, more reliability, more intelligence and serving more targets at the same time. The development and application of RF digital technology provides solutions to achieve the above goals. The RF digitization of TT&C system is faced with some problems caused by multi channel asynchronization, such as ranging zero jitter and large delay jitter of TT&C data. In this view, this paper proposes a multi channel synchronous and deterministic delay method for solving these problems. The test data show that the data delay jitter is controlled in the order of 0.02 μs, and the zero value stability of the system ranging improves by 60% (RMS 0.48 m). These test results verify the effectiveness of the scheme. |
