摘　　要：为了满足海洋、内河近距离导航,X波段线性调频雷达正逐渐得到应用。文章将DDS(Direct Digital Synthesis)技术与倍频及混频电路相结合,提出了X波段线性调频连续波雷达发射机的设计方案,对关键模块进行实现,并阐述了PCB(Printed Circuit Board)板的设计流程。实验结果表明该方案很好满足了对X波段线性调频信号的要求。In order to meet the ocean, the river near the navigation, LFM radar is gradually applied in X- baod. Taking joint con- sideration of DDS technology,frequency multiplier circuit, and mixer circuit, a X-band continuous-wave radar transmitter with linear frequency modulation is designed. Specifically, the key circuit is realized, and the design of PCB board is explicitly. The experimental results show that the proposed scheme can generate required the X- band chirp signal.
