| A simulation signal source is required to provide echo signal to the Synthetic Impulse and Aperture Radar(SIAR) signal processor when it is developed and debugged in laboratory. In this paper, the principle for SIAR is introduced firstly, and the forming of echo signal and the signal synthesis is analized particularly.Then,the computer simulation on arithmetic of the simulation signal source is gived.On that basis,the realization based on software and hardware is provided.The software flowchart and relative circuit design in the software realization is described in detailed,as well as the hardware relatization based on ADSP2 1062 is introduced. |
