Advanced Techniques of Spaceborne Surveillance Radar

Dear Colleagues,

Spaceborne radars play a significantly increasing role in civil and defense applications due to their global observation and surveillance ability. Spaceborne synthetic aperture radars have gone through a long history and are widely used today. In contrast, spaceborne radars for surveillance and warning purposes have rarely been reported commercially due to several technique difficulties and a high efficiency–cost ratio. Nevertheless, it is important to develop spaceborne surveillance radar systems to enable a safer world. Basically, spaceborne radar systems have the characteristics of high orbital speed, large operational range, and extremely varied dynamics of space temperature. A slow-moving target buried in the ground/sea clutter background is the key challenge for spaceborne surveillance radar systems.

This Special Issue discusses moving target detection under strong clutter background and/or dense jamming environments by spaceborne surveillance radars. Topics of interest include spaceborne radars, space–air bistatic radars, large reflector antennas, phased array antenna calibration, digital beamforming, waveform diverse arrays, spaceborne moving target detection, multi-target tracking and localization, space-time/space-time-frequency adaptive processing, non-homogeneity ground/sea clutter suppression, range and Doppler ambiguous clutter suppression, anti-jamming techniques, spaceborne radar and communication co-existence, beyond linear processing, and so on.

It is important and meaningful to jointly explore system designs and signal processing techniques in order to solve the most difficult issues regarding radars and to meet new application demands. Possible solutions include sophisticated system designs for antenna systems all the way to signal and data processing, advanced signal processing techniques by exploiting the characteristics of clutter and moving targets, sophisticated array signal processing and algorithms by optimally choosing the parameters or structure of the algorithms, novel designs of radar systems by introducing waveform diversity, cooperated signal processing with multi-static or distributed radar systems, etc.

Spaceborne radar techniques are well related to the journal. The topics of interest, from system design, antenna, and signal processing, to data processing, are all very important for Remote Sensing.

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. Remote Sensing 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 2700 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.
