Design of a high-speed intermediate frequency radar signal generator

The design and realization of a universal intermediate frequency radar signal generator system has been brought forward, basing on FPGA technique. The principle and realization of high speed digital up convert (DUC) has been introduced. A novel approach of reducing the phase truncation spurs in numeric control oscillator (NCO) has been proposed as well. Finally, the hardware configuration has been described. The experimentations show that the signal generator is a universal equipment and it can be applied in different radar systems.
