Abstract

We present an approach to high-resolution direction-of-arrival estimation for distributed radar sensors without the need for synchronization or wired connections. The sensor signals are post-processed and combined after range-Doppler processing achieving a larger virtual aperture and multiple snapshots. The proposed approach is validated via simulations and the effectiveness is compared to other baseline estimators with respect to estimation accuracy and resolution performance. Finally, the applicability on real data is demonstrated using a simple measurement setup in an anechoic chamber.
基于分布式雷达传感器的高分辨率到达方向估计
我们提出了一种不需要同步或有线连接的分布式雷达传感器的高分辨率到达方向估计方法。传感器信号经过距离多普勒处理后进行后处理和组合,实现更大的虚拟孔径和多快照。通过仿真验证了该方法的有效性,并将其与其他基线估计器在估计精度和分辨率性能方面进行了比较。最后,利用消声室中的简单测量装置验证了该方法在实际数据上的适用性。
