Special Issue Information
Dear Colleagues,
Multichannel radar refers to a radar with multiple transmitting or receiving channels, which can exist in various forms such as single-input multi-output (SIMO), multi-input single-output (SIMO) and multi-input multi-output (MIMO). Due to its higher degree of freedom, multichannel radar has significant advantages in fields such as object detection and imaging, and it has received widespread attention in recent years.
For example, multichannel radar can perform instantaneous single snapshot processing with high processing efficiency, but often faces the problems of poor angular resolution performance caused by small aperture size and grating lobe suppression introduced by sparse channel arrangement. At the same time, multichannel radar can also be installed on motion platforms for coherent processing, such as coherent accumulation detection, synthetic aperture radar (SAR) imaging, etc., to obtain higher processing gains. Moreover, it inevitably introduces multichannel error estimation and compensation problems. In addition, multichannel radar often faces coupling problems between channels.
This Special Issue aims to gather the latest research results and highlight the advances of multichannel radar, with topics including the following: imaging algorithms, parameter estimation, motion compensation, super-resolution, anti-jamming, direction of arrival (DOA) estimation, array calibration and other signal processing technologies of multichannel radar or multichannel SAR.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
