| Abstract: | A verifiable platform of wideband high-dynamic full digital radar receiver based on the new ADC AD9680 was designed for demands of bandwidth,dynamic,processing speed and multichannel.First,results of performance and analysis were acquired in full-bandwidth mode and DDC mode on the platform of AD9680.Solutions of AD9680 to improve dynamic performance were proposed based on the results.Then,dual-channel synchronization of AD9680 was verified and a method of optimizing dual-channel time deviation was proposed.All test results in this article showed that AD9680 would meet the requirements of certain wideband radar. |
