Special Issue Information

Dear Colleagues,

Radio frequency (RF) is a common resource used in wireless communication and radar. In the past, wireless communication and radar were considered to be conflicting due to the interference between them; however, with the development of RF technologies, people have found that wireless communication and radar can co-exist harmoniously. For example, positioning the receiver can help the transmitter direct the communication signal more accurately toward the mobile receiver via beamforming. Conversely, distributed radar systems have a higher resolution by communicating the sensing data. In addition, dual-function radar-communication systems have also emerged. Therefore, wireless communication and radar can benefit from each other, which becomes a significant trend for future wireless communication and radar systems.

This Special Issue aims to present state-of-the-art research in wireless communication and/or radar-related technologies. Topics of interest include (but are not limited to) the following:

  • 6G;
  • Radar signal processing;
  • Integrated sensing and communication;
  • Semantic communication;
  • Reconfigurable intelligent surface;
  • Machine learning;
  • Resource allocation and management;
  • Information theory;
  • Joint source-channel coding;
  • Security.

This review paper provides a comprehensive examination of millimeter-wave radar technologies in automotive systems, reviewing their advancements through signal processing innovations. The evolution of radar systems, from conventional platforms to mmWave technologies, has significantly enhanced capabilities such as high-resolution imaging, real-time tracking, and multi-object detection. Signal processing advancements, including constant false alarm rate detection, multiple-input–multiple-output systems, and machine learning-based techniques, are explored for their roles in improving radar performance under dynamic and challenging environments. The integration of mmWave radar with complementary sensing technologies such as LiDAR and cameras facilitates robust environmental perception essential for advanced driver-assistance systems and autonomous vehicles. This review also calls attention to key challenges, including environmental interference, material penetration, and sensor fusion, while addressing innovative solutions such as adaptive signal processing and sensor integration. Emerging applications of joint communication–radar systems further presents the potential of mmWave radar in autonomous driving and vehicle-to-everything communications. By synthesizing recent developments and identifying future directions, this review stresses the critical role of mmWave radar in advancing vehicular safety, efficiency, and autonomy. Full article
