Pitfalls and possibilities of radar compressive sensing

In this paper, we consider the application of compressive sensing (CS) to radar remote sensing applications. We survey a suite of practical system-level issues related to the compression of radar measurements, and we advocate the consideration of these issues by researchers exploring potential gains of CS in radar applications. We also give abbreviated examples of decades-old radio-frequency (RF) practices that already embody elements of CS for relevant applications. In addition to the cautionary implications of system- level issues and historical precedents, we identify several promising results that RF practitioners may gain from the recent explosion of CS literature.
