摘要
Abstract
A new radar signal simulator was designed to provide an effective validation method for some radar signal process algorithms. A new DSP + FGPA + DDS architecture is introduced, in which DSP acts as central processor and AD9957 as basic target signal generator. The FPGA provides the base band data for up-frequency-convertion chip AD9957 under the control of DSP to generate middle-frequency analog signals. A multiplier based iterative algorithm is employed innova-tionally to simulate multiple radar echo signals. The simulator is good at wide-time-domain simulation. The new architecture can save more hardware resources in generating multiple targets and difference signals than traditional methods. The system has the features of high integration, flexible expansion and effective data generation.关键词
