Special Issue Information
Dear Colleagues,
Four-dimensional millimeter-wave radar (4D mmWave radar), capable of simultaneously capturing distance, azimuth, elevation (height), and radial velocity of targets, has become a key advancement in intelligent sensing systems. Unlike traditional 3D radar, 4D mmWave radar excels in angular resolution, spatial 3D perception, and dynamic velocity measurement, making it highly applicable in autonomous driving, intelligent transportation, robotics, and smart infrastructure monitoring.
While traditional radar is limited to measuring distance, azimuth, and velocity, 4D radar’s ability to capture height data enables precise 3D positioning and multi-target recognition, especially in complex environments. The development of large-scale MIMO antennas and advanced signal processing has further enhanced its capabilities, supporting comprehensive spatial modeling and dynamic sensing.
This Special Issue seeks high-quality research on 4D mmWave radar, covering design theory, hardware, signal processing, point cloud generation, multi-modal fusion, and applications in autonomous driving, robotics, unmanned systems, intelligent transportation, and outdoor emergency rescue. We particularly welcome research on integrating robotic and intelligent agent perception with 4D mmWave radar.
The key topics of this Special Issue include, but are not limited to, the following:
- Signal processing and system design methods for 4D mmWave radar;
- Multi-antenna MIMO configurations and high-resolution array optimization;
- Integration of 4D mmWave radar with robotics/intelligent agents;
- Multi-modal data fusion (with cameras, LiDAR, IMU, etc.);
- Algorithms and systems for 4D mmWave radar in autonomous driving perception;
- Intelligent transportation, smart infrastructure, and vehicle-road collaborative sensing applications;
- Efficient real-time processing and embedded implementation;
- Outdoor emergency rescue and applications in complex environments;
- Radar perception robustness, anti-jamming, and safety analysis.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
