In order to achieve high-precision clock synchronization among instrument nodes in distributed LXI bus test systems. A Hardware time stamping method for PTP messages is introduced in this paper. It is implemented in Linux systems, which runs on ARM9 S3C2440 processor. The special PHYTER DP83640 is used to mark the time of PTP messages in ...

In order to make radar target track simulation more realistic in simulation test-bed of C3I system, a new method which utilizes data mining techniques based on historical radar data is proposed. This method includes two stages: The first is “Filtering separation – piecewise fitting – feature clustering”. In this stage, the radar historical data is ...
