From mmWave Radar Nodes to Multistatic Arrays: Design Considerations and Applications

The potential of single-node mmWave radar systems can be expanded with more sophisticated configurations: multi-frequency, multistatic, or phased-array radars. Several radar nodes have been designed with emphasis on transitioning to mul-tistatic or phased-array configurations. This approach involves addressing critical factors often overlooked by commercial radar systems, including synchronization and data handling. This paper presents a 120 GHz phased-array radar, comprising 15 individual nodes. Additionally, we highlight the potential advantages of incorporating phased-arrays and multistatic radars in biomedical and structural health monitoring applications.
