Un système d’échantillonnage haute vitesse et haute résolution constitue l’élément crucial des récepteurs radar à large bande. Un système d'échantillonnage à large bande de 10.4 GS/s 12 bits basé sur la technique TIADC est conçu dans cette lettre. La fonction d'acquisition est implémentée sur une plateforme VPX. La fonction de stockage est implémentée sur un serveur rack standard de 19 pouces. Les données échantillonnées sont transmises à grande vitesse via des fibres optiques entre elles. Une méthode d'étalonnage mixte basée sur une reconstruction parfaite est adoptée pour compenser les inadéquations de canaux du système TIADC à large bande. Pour les signaux sinusoïdaux de 100 MHz à 5000 46 MHz, plus de 56 dB SNDR et XNUMX dB SFDR peuvent être obtenus dans ce système d'échantillonnage. Cette lettre fournit un schéma d'acquisition à grande vitesse et haute résolution pour les récepteurs numériques à large bande à échantillonnage direct de fréquence intermédiaire.

Abstract: A high-speed high-resolution sampling system is the crucial part in wideband radar receivers. A 10.4-GS/s 12-bit wideband sampling system based on TIADC technique is designed in this letter. The acquisition function is implemented on a VPX platform. The storage function is implemented on a standard 19-inch rack server. The sampled data is transmitted at high speed through optical fibers between them. A mixed calibration method based on perfect reconstruction is adopted to compensate channel mismatches of wideband TIADC system. For sinusoidal signals from 100MHz to 5000MHz, more than 46-dB SNDR and 56-dB SFDR can be obtained in this sampling system. This letter provides a high-speed and high-resolution acquisition scheme for direct intermediate frequency sampling wideband digital receivers.
