Abstract :
A complete method of synchronization technology of bistatic radar using global position system (GPS) is presented. The time benchmark signal 1PPS was elaborately modified in order to increase the time synchronization precision. A very high time synchronization precision was achieved. Using the modified 1PPS to discipline the local VCXO, the reference frequency signal both achieve a high long term stability (LTS) and short term stability (STS) property. The experimental results show that the time synchronization precision of our synchronization system can be improved from plusmn100 ns to plusmn25 ns. Well, the STS reach 2times10-11/s and the phase noise is improved 20 dB comparing with the results
