Antenna-array design in compressive-sensing radar systems

Compressive sensing (CS) in radar is presented at the system level with emphasis on the front end that keeps the functionality of data acquisition. In CS, the data acquisition is compressive as it delivers fewer measurements. We explore spatial compressive acquisition of radar measurements by the existing means available in a radar system: design of antenna arrays (AA), and focus here on active co-prime arrays. The back end is also involved with sparse-signal processing (SSP). Numerical results show the AA suitability for compressive acquisition and for the SSP with optimal processing gain.
