摘要
采用剩余定理设计多基线干涉仪，并通过一套系统的设计、仿真证明其有效性和准确性。简要介绍了其基本实现过程，并通过引入数字接收技术提高其工程实践指导意义。该干涉仪采用超外差结合超宽带数字接收技术实现，工作频段覆盖2～18GHz，数字中频带宽可达到400MHz；同时采用数字信道化技术，进行数字瞬时测频（IFM）辅助测向结果生成。
The remainder theorem is used to design multi baseline interferometer,And through a set of system design and simu-lation prove the effectiveness and accuracy. Its basic implementation process are briefly introduced, and through the introduction of digital receiving technology to improve its engineering practice guiding significance . The interferometer adopts superhetero-dyne ultra wideband digital receiving technology implementation, 2-18 GHZ frequency coverage, digital intermediate fre-quency bandwidth can be up to 400 MHZ;Adopting digital channelized technology at the same time, digital instantaneous fre-quency measurement （IFM） auxiliary direction finding results generated.
