DDS Based Radar Signal Generator for Microwave Remote Sensing

摘要：

A system design of a Direct Digital Synthesis (DDS) based radar signal generator is presented. The DDS technique has its inherent disadvantage in noise and spurious suppression, due to the all-digital structure. To overcome these disadvantages, we apply two effective methods of a 3-order low-pass Butterworth filter and the pre-distortion technique to greatly enhance the system performance.
