| 摘 要： | 同步是双基地雷达的关键技术之一,该相位同步系统采用双向相位传递法,在收、发站分别测量相位差,再将两个相位差值相减得到相位补偿值。通过对相位同步信号采样,加窗,用FFT谱分析法测量相位差值,通过仿真证明该方法可精确测得相位差值,完全可达到双基地雷达相位同步要求。

| Abstract: | Synchronization is one of the key technologies of bistatic radars.The phase synchronization system designed uses two-way phase transfer which measures the phase differences both at the receiver and the transmitter,and then gets the compensation phase through the subtraction operation between the two phase differences.The phase synchronization signals are sampled,windowed and the FFT transfer is used to get the phase differences.The results of simulation show that this system can get the precise phase difference,and can meet the requirement of synchronization of bistatic radars. |
