Digital technology permeates electronic design, especially in the field of radar. This paper describes some ways in, which digital technology is used to overcome the limits of analog circuits, particularly in waveform generation, signal processing, and clutter suppression. Another example of the application of digital technology to radar is the general-purpose computer that is part of every modern radar. The ability of state-of-the-art computers to support radar requirements is surveyed, and future capabilities are projected.
