The system design,simulation,implementation and experiment conclusion of a multiple baseline digital interfero-meter which is under the condition of outside application are introduced to illustrate that the remainder theorem has a relatively rigid logic and accuracy for the application in interferometer design. To introduce the digital receiving technology into interfero-meter system to ensure the high performance is rational and feasible,and is in line with the development trend of electronic countermeasures,which makes the system design method is more significance. The ultra wideband digital technology is adopted to implement the interferometer with digital IF bandwidth of 400 MHz. It has been applied to a single station positioning experi-ment system,and its application effect is good.
