The high-precision time synchronisation is of vital importance in the modern communication, navigation system and weapon system. The microwave time transfer method is adopted to resolve the time synchronisation problem. After expounding the principle and system composition of the method, the microwave time transfer system has been constructed. First, the measurement of board-level and system was conducted. The transfer bandwidth in the experiment via microwave channel is 10 Mb. The results show that the jittering of retrieval signals via microwave channel is <4 ns. Then the microwave transmission experiment of 23 km was carried out. The results show that RMS error of time signal is <2 ns and the error between the forward and backward directions is <4 ns.
