two-way voice transmission

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.

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。
