Abstract :
A new design for digital down conversion (DDC) in Ocean State Measuring and Analyzing Radar (OSMAR) is presented. Some examples are given, and the result can prove the validity. All parameters can be adjusted freely according to our needs, and the new system can be adapted to the next generation HF system OSMAR.
