Processing of Stepped-Frequency Radar Echo Sample Data

This paper first analyzed the block diagram of the millimeter-wave stepped-frequency radar mathematical and introduced the theoretical derivation of the high range resolution profiles. Then we presented the sampling card AC6684 and the trigger card in the data sampling system and completed the circuit design of the trigger card. Finally, the MFC is used to achieve the IFFT processing of the sampling data. After considering the range ambiguity and the range resolution we got the high range resolution profiles of the stepped-frequency radar.
