摘　　要：建立了多信道相控发射机的系统模型,为了满足该系统模型在空间波束合成过程中射频信号同频同源、相位可控的要求,提出了一种高精度的多信道射频信号的相位检测技术。该技术基于数字信号处理,可以精确有效地检测不同信道之间的相位差,为实现射频信号的信号同步提供了可能。经过实际发射系统的实验证明,该技术能够并行检测多信道射频信号的相位,成功实现了多信道射频信号的同步。This paper proposes a system model of a multichannel phased transmitter. To meet the require- ment of the same frequency of homologous and the controllable phase of RF siganal for space beamformer in the system model, a high-precision multichannel RF signal phase detection technology is presented. Based on digital signal processing, the technology can detect different channel phase difference accurately and ef- ficiently. It is possible to achieve the synchronization signal of the RF signal. The experiments of the actual launch system show that the technology can detect the phase of multichannel zing the synchronization of multichannel RF signal successfully.
