摘　　要：针对电子战中敌方雷达的快速定位,设计了一种基于三基线干涉仪的二维瞬时测向系统,解决了在宽频带范围内保证测向视角和精度的难题。给出了系统的工作原理、电路结构以及软件算法,并重点介绍了信号处理组件的设计等关键技术。试验结果表明,该测向系统在X波段全频带内的测向视角达到了±60°,测角精度优于1°。The two-dimensional instantaneous direction finding system based on three-baseline interferometer technology is designed for locating enemy radar in electronic warfar. The problem of meeting direction finding system＇s angle range and precision in wide wave band is solved. The system＇s working principle, circuit structure, as well as sofeware arithmetic are discussed. Some key technique, for example, the design of signal processing unit is introduced especially. The test result indicate that the directiorl finding system＇s angle range has reached ±60°, its precision is better than 1° in X band.
