Abstract:A virtual instrument based integrated measurement system for Doppler navigation radar is developed.Using direct digital synthesis(DDS)technique,a kind of radar Doppler frequency simulator is introduced.High reliable PXI Bus system is used to construct its hardware architecture and LabWindows/CVI is used as software development tool.The application of the system shows that it has many ad- vantages such as easy to use,convenient operation,operate at real time and expandable.
Keywords:Doppler navigation radar  direct digital synthesis  virtual instruments PXI Bus
