摘　　要：针对内河绿色智能船舶船岸一体化信息系统的需求,提出了一种多通道、宽动态、高灵敏度的接收机射频前端设计方法。介绍了接收机射频前端的架构设计,通过数理推导确定了射频链路的设计方案。研制了一款可应用于水上移动业务领域的VDES(甚高频数据交换系统)射频前端,该射频前端包括7路射频通道,具备对AIS、ASM、VDE和DSC信号的接收和发射功能。通过实际加工和测试,测试结果与预设值吻合较好。并将射频前端与整机进行装配实验,实验结果表明,接收动态范围≥110 dB,AIS接收灵敏度≤-117 dBm,相邻信道选择性≥70 dB,证明该射频前端设计方法具有可行性。According to the requirements of the integrated technology for green intelligent inland ship,a receiver RF front-end design method of multi-channel,wide dynamic and high sensitivity is proposed.This paper discusses the architectural design of the receiver RF front-end,and obtains the design solution through mathematical derivation.Then,a VDES(VHF Data Exchange System)RF front-end is developed,which can be applied in water mobile business area.This RF front-end includes 7 RF chan‐nels with receiving and transmitting functions for AIS,ASM,VDE and DSC.Finally,through actual processing and testing,the test results are precisely consistent with the preset values.At the same time,this RF front-end is assembly tested in whole machine,and the test results show that the receiving dynamic range is more than 110 dB,the receiving sensitivity is less than-117 dBm of AIS,and the adjacent channel selectivity is more than 70 dB,which proves that the RF front-end design method is effective.
