THE DESIGN OF DIGITAL RADAR RECEIVERS

With the development of digital processing technology, there are emerg ing trends toward digitization in radar receivers design. By applying direct intermediate frequency-to-digital conversion (IF sampling) and direct digital synthesis (DDS), digital radar receivers can be designe d. The digital radar receivers can obtain much higher precision and st ability than analog ones; moreover, it can retain the extreme flexibil ity of digital techniques. This paper presents the principle, constitu tion and design method of digital radar receivers.
