| Abstract: | In digital IF receiver based on IF sampling technology, one important issue of system design is how to realize wide instantaneous dynamic range, when the available digits of AD converter is limited. By analyzing various factors related to the dynamic range, a new method of realizing wide instantaneous dynamic range in radar receiver based on IF sampling technology is proposed in this paper. |
