The Design of Radar Digital Intermediate Frequency Test System
نویسنده
چکیده
To satisfy the requirement of high performance signal processing technique, it is necessary to use the direct sampling of intermediate frequency signal to obtain quadrature signals. Digital intermediate frequency (DIF) system is widely used in radar and communication system. This paper briefly introduces the principle of test system based on DIF. We design this DIF test system to test the performance of ADC and I/Q. The design has the advantages of convenient use, and reliable performance.
