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.

协素数阵列的反卷积传统波束形成
协质传感器阵列(CSA)由于其阵列配置的“协质”性质,最近受到了很多关注,该阵列使用较少的传感器产生高分辨率,类似于使用传统波束成形(CBF)的大孔径均匀线性阵列(ULA),使用更多的传感器。与ULA相比,CSA产生更高的旁瓣和更小的检测增益。本文将CBF应用于CSA,然后对CBF光束输出进行反卷积,称为反卷积CBF。仿真结果表明,与乘积处理及其扩展相比,反卷积CBF具有更高的分辨率、更高的增益和更低的副瓣。
