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.
