Radar signal synchronization system

The invention discloses a radar signal synchronization system comprising a host device and at least one slave device. After filtering a signal source, the host device performs down-conversion processing to obtain an intermediate-frequency signal; conversion is carried out to obtain a zero-frequency signal; after digitization processing, an optical signal processing unit of the host carries out conversion to obtain an optical signal; the optical signal is transmitted to the slave device through a fiber; and the slave device receives the optical signal, carries out the reverse operation, and then sends the processed signal to a transmitting system for external transmission. After processing by the host device and the slave device, delay synchronization of multiple devices is ensured effectively; the networking cost is saved; and a defect of restriction by the website distance is overcome by the fiber transmission. 本发明公开了种雷达信号同步系统，包括主机设备及至少个从机设备，主机设备将信号源滤波后，进行下变频为中频信号，再变换为零频信号，经数字化处理后，经主机光信号处理单元转换为光信号，由光纤传输到所述从机
