Multi-Sensor and Multi-Channel Systems and Technology: Advances, Challenges and Opportunities

Dear Colleagues,

In recent decades, multi-sensor and multi-channel systems have attracted much attention from both academia and industry. Modern systems equipped with a range of sensors, multi-channel electronics, and advanced array processing capability have gained momentum in almost all application areas, including radar, mobile communications, underwater sonar, non-destructive evaluation, healthcare, sensing and imaging, wireless charging, and unmanned vehicles. The collaborative processing of multi-sensory and array data allows for many advantages and makes systems much more powerful, intelligent, flexible, robust, and reliable, usually with less cost. However, current sensor array systems and technology still suffer from critical challenges in order to meet ever-increasing demands and expectations. The recent advances in sensor design, new materials, electronics, array algorithms, computation, and artificial intelligence technologies have promising potential to overcome some of the key challenges.

Most of the challenges encountered in multi-sensor systems and technology still need to be researched, regardless of the applications. Many limitations exist in various application environments, and research questions remain open. This Special Issue provides a platform to share the most recent developments in this field, and we look forward to the latest research findings that suggest theories and practical solutions for various applications using array technology and systems.

Authors are encouraged to submit contributions in any of the following or related areas:

• Modern radar systems
• Wireless communication
• Non-destructive testing and evaluation
• Healthcare applications and systems
• Underwater vehicles and applications
• Antenna arrays and smart antennas
• Acoustic microphone arrays
• Ultrasound transducer arrays
• Phased array processing and multi-channel systems
• Beamforming and direction-of-arrival (DOA) estimation
• Artificial intelligence

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. Electronics 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 2400 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.
