Abstract
Coprime Sensor Array (CSA) has received a lot of attentions recently due to "coprime" nature of the array configuration, which yields a high resolution using product processing with fewer sensors, similar to that of a uniform liner array (ULA) of a larger aperture using conventional beamforming (CBF), with more sensors. Compared with the ULA, CSA yield higher sidelobes and less detection gain. This paper applies CBF to the CSA and then deconvolution to the CBF beam output, referred to as deconvolved CBF. Simulation results show that deconvolved CBF yields a higher resolution, higher gain and lower sidelobes than the product processing and its extensions.
