High-resolution imaging using a narrowband MIMO radar system

摘要：

This paper presents a system model and method for the two-dimensional (2-D) imaging application via a narrowband multiple-input multiple-output (MIMO) radar system with two perpendicular linear arrays.The proposed method utilities the spatial parallel procedure sampling the scattered echoes during a single snapshot illumination,instead of the spatial sequential one sampling the scattered echoes during multiple snapshot illuminations in inverse synthetic aperture radar (ISAR) imaging.Consequently,the complex motion compensation in ISAR imaging can be avoided.Furthermore,in our array configuration,multiple narrowband shared-spectrum waveforms coded with orthogonal ployphase sequences are employed to illuminate a target.The mainlobe of the compressed echoes from the different filter band for all scatterers could be located in the same range bin,and thus,complex range alignment in classical ISAR imaging is not necessary.Numerical simulations based on synthetic data are provided for testing our proposed method.
