Background

Compressive sensing (CS) is a novel acquisition and processing theory that enables reconstruction of sparse signals from a set of non-adaptive measurements sampled at a much lower rate than required by the Nyquist-Shannon sampling theorem as pertaining to the full signal bandwidth. In the NATO framework, the SET-213 Specialist Meeting on Compressed Sensing for Radar/SAR and EO/IR imaging that took place in Tallinn, Estonia, in May 2014 provided an opportunity for specialists in this research field to come together, present the current state-of-the-art of CS and where investment is needed to propel CS radar and EO/IR systems to the next level. The applications discussed during the Specialist Meeting emphasized several advantages of using CS based systems, and as a result in 2014-2015 two Exploratory Teams (ETs) were started. At the end of the ETs, two Task Groups (SET-232 and SET-236) were created to further investigate the potential of CS applied to radar and ESM (SET-236) and to EO/IR imaging (SET-232). Both TGs received broad consensus amongst several NATO nations. After 5 years, CS theory and applications have evolved and this SM would be the opportunity to showcase the latest scientific and technological results. Moreover the level of maturity that has been reached in this field is getting closer to real implementation and operational use. Again this SM would be a common ground for representatives from academia, industry and military to foster discussions between CS experts, fully understand the benefits and limitations of CS, and identify the remaining gaps where investment will be most advantageous for NATO.

Objectives

The aforementioned TGs are ending in 2018, and the objective of the SM will be to 1) review the achieved results in this area within the TGs during the past few years, 2) attract people outside the TGs to present their latest results and ideas, 3) identify areas where successful breakthroughs in CS radar or EO/IR systems can be applied to the other domain and 4) promote round table discussion to stimulate cross-fertilization of ideas for future research. The outcome of the SM will be a technical report and the collection of all authors’ papers and presentations.
