摘　　要：介绍了一种阵列信号频分复用毫米波传输技术。采用分组二次上变频频谱装配频分复用和解复用技术,实现多路阵列信号在一条宽带毫米波链路上进行双向传输。通过设计控制和幅相校正技术保证了阵列信号分量间的良好幅相一致性。完成了30路阵列信号传输设备研制并进行了测试,结果证明了技术方案的可行性。该技术可以应用到多路阵列信号的毫米波传输中。The millimeter wave（MMW） transmission technology for frequency division multiplexing（FDM） array signals is introduced. For realizing bidirectional transmission of multi - channel array signals on a wide band MMW circuit link, the technology of frequency division multiplexing and demultiplexing of grouping two frequency upconversion spectral assembly is adopted. By the design control and the correction of phase and amplitude, a good phase and amplitude coherency between array signals is guaranteed. A prototype with 30- channel array signals transmission is fabricated and tested. The test results demonstrate the scheme is feasible. The tech- nology can be used in the MMW transmission of multi - channel array signals.
