Recent Advances in Millimeter-wave Radar Research

Millimeter-wave (mmWave) radar is a type of radar that uses electromagnetic waves in the millimeter-wave frequency range, which is between 30 and 300 GHz. MmWave radar has a number of advantages over traditional radar, such as higher resolution, better penetration in fog and rain, and the ability to be miniaturized. As a result, mmWave radar is being increasingly used in a variety of applications, including automotive radar, drones, and indoor sensing.

Here are some of the latest research areas in mmWave radar:

• High-resolution imaging: MmWave radar is now capable of achieving sub-millimeter resolution, which is enabling new applications such as gesture recognition and facial recognition.
• Multiple-target tracking: MmWave radar can track multiple targets simultaneously, which is important for applications such as autonomous vehicles and air traffic control.
• Fusion of mmWave radar with other sensors: MmWave radar is often fused with other sensors, such as cameras and lidar, to create a more complete picture of the environment.
• Artificial intelligence (AI) in mmWave radar: AI is being used to improve the signal processing capabilities of mmWave radar and to develop new algorithms for target recognition and classification.
