“…A significant advancement occurred in the mid-1970s with the introduction of digital signal processing for the extraction of range information from received signals. Before the availability of digital processing, earlier FMCW radar systems, like those mentioned earlier, relied on single band-pass filters to detect signals at specific range gates, which was highly inefficient in terms of radar observation time [22]. Conversely, FMCW radio altimeters have long utilized a closed-loop system to adapt the sweep duration to maintain the beat frequency from the ground within a single range bin.…”

Frequency-modulated Continuous-wave (FMCW) radar is a powerful sensing technology. It is widely used in various applications. This paper presents an in-depth exploration of the FMCW radar signal generation using Direct Digital Synthesis (DDS) technology. DDS offers precise and flexible control over the frequency modulation required for FMCW radar systems. The fundamental principles of FMCW radar were delved into in this study, with emphasis placed on the importance of continuous frequency modulation in achieving accurate range and velocity measurements. We discuss the essential components of an FMCW radar system, focusing on the critical role played by DDS in generating the required frequency-modulated signal.
