| Abstract: |
| Radar target echo simulation system is widely used in the development and production of radar equipment, the accuracy of its simulation is very important. A radar target echo simulation method based on digital radio frequency memory（DRFM）, combined with digital composite modulation and high?speed comprehensive calculation and distribution is proposed in this paper. The range simulation accuracy and velocity simulation accuracy of the radar target echo simulation system designed and implemented by this method are tested and verified. The results show that the radar target echo simulation method described in this paper can provide high?precision radar target echo for debugging, experiment and checkout of radar equipment. It provides some guidance and reference for high?precision simulation of radar target echo. |
