【Abstract】 The design and realization of software and hardware of the simulation signal source for the frequency stepped radar based on DSP is presented, with emphasis on the generation of video echo signals and the “softwaren hardware” which means how to generate the moving wavegate using on chip timers of DSP and how to transfer noise data using on chip DMA. Finally, the signal from the source is verified.更多还原
