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.
Here are some examples of recent research results in mmWave radar:
- In 2023, Continental AG released a new 77GHz mmWave radar that has a 120-degree by 180-degree field of view and a maximum detection range of 250 meters. https://www.continental.com/en-us/press/press-releases/next-gen-short-range-radar/
- In 2022, Robert Bosch GmbH released a new 4D mmWave radar that can provide the azimuth, range, elevation, and velocity of targets. https://www.bosch-mobility.com/en/solutions/sensors/front-radar-sensor/
- In 2021, Huawei Technologies Co., Ltd. released its first commercial vehicle-mounted mmWave radar, which operates at 77GHz and has a maximum detection range of 200 meters. https://e.huawei.com/en/products/wireless/microwave/asn850-radar
Overall, mmWave radar is a rapidly developing technology with a wide range of potential applications. As mmWave radar technology continues to improve, we can expect to see even more innovative applications in the future.
