压缩感测是一种结合压缩及采样的技术,对於在某些变换域有稀疏性质的信号非常有效率.最近,压缩感测被提出用於雷达系统.当雷达目标在多普勒-距离空间中是稀疏的,压缩感测回复技术可以有效的重建出目标物.在本文中,我们将这个想法延伸到多进出雷达.在多进出雷达,本文使用压缩遥感技术去重建目标物於多普勒-距离-角度空间.为了有效地重建目标物,目标物的反射信号的相关性必需要足够小.本文提出了一种波形设计的方法,以减少目标物反射信号之间的相关性.由於多进出雷达的维度较大,压缩技术将会是影响力相当大的技术.
Compressed sensing is a technique for efficiently sampling signals which are sparse in some transform domain.Recently,the idea of compressed sensing has been used in the radar system.When the number of targets on the range-Doppler plane is small,the target scene can be reconstructed by employing the compressed sensing techniques.In this paper,we extend this idea to the MIMO radar.In the MIMO radar,the compressed sensing technique can be used to reconstruct the target scene when the signals are sparse in the range-Doppler-angle space.To effectively reconstruct the target scene,it is required that the correlation between the target responses be small.In this paper,a waveform design method is introduced to reduce the correlations between target responses.Because of the increased dimensionality in MIMO radars as compared to SIMO radars,the impact of compressed sensing will be very significant there.
