Integrated Phased-Array Frequency-Modulated Continuous-Wave Radar Transceivers on Silicon

In the rapidly evolving field of radar technology, frequency-modulated continuous-wave (FMCW) radars have emerged as a fundamental innovation, especially in their integrated form in CMOS/BiCMOS technology. These radars are known for their compactness, cost-effectiveness, and high functionality, making them ideal for many applications ranging from disaster relief, automotive safety, and autonomous driving to imaging and industrial remote sensing. However, the evolution of FMCW radars has encountered certain limitations, particularly in terms of directional capabilities and spatial resolution. This is where the integration of phased arrays plays a transformative role. This advancement allows for enhanced target detection, improved spatial resolution, and the ability to track multiple objects simultaneously. This survey aims to explore these advancements by examining innovative developments in the integration of phased arrays into FMCW radars on silicon and their applications.
