一种有效的稀疏天线阵列架构的相干成像稀疏,但在其他方面未知的场景。在这种架构中,阵列元件形成周期性的非均匀图案。使用分析,明确考虑到噪声的存在,我们开发了一个有效的模式设计过程的基础上,共同阵列,描述了一个有效的场景支持恢复算法的一部分,图像重建的形式修改的MUSIC算法,并讨论了故障检测技术的基础上评估“反投影”错误。由于我们的开发利用了一个密切的连接到多陪集采样的带限波形,我们的结果可能反过来也可能是有用的,在这些系统的设计。
An efficient sparse antenna array architecture is developed for coherent imaging of sparse but otherwise unknown scenes. In this architecture, the array elements form a periodic nonuniform pattern. Using analysis that explicitly takes into account the presence of noise, we develop an efficient pattern design procedure based on co-arrays, describe an efficient scene support recovery algorithm as part of image reconstruction in the form of a modification to the MUSIC algorithm, and discuss a failure detection technique based on evaluating “back-projection” error. Since our development exploits a close connection to multi-coset sampling of bandlimited waveforms, our results may in turn may also be useful in the design of those systems.
