Design of wideband radar signal simulator based on high-speed DDS technology

摘要

Radar signal simulation technology plays an important role in the development, performance and evaluation testing stage of modern radar systems. This paper focuses on the design principles and hardware components of a wideband radar signal simulator based on high-speed DDS technology and Compact PCI bus. The result of joint commissioning between computer software and hardware system shows that this simulator can generate a variety of radar signals reliably and switch quickly among these signals. It is of good practical value in engineering practices.
