针对L形阵调频连续波(FMCW)雷达,提出了一种基于三维子空间的方位角、俯仰角和距离自动配对估计方法。所提出的方法被设计为利用堆叠的汉克尔快照矩阵的3D平移不变结构进行自动配对的方位角、仰角和距离估计。通过在室内进行的各种实验验证了所提出方法的有效性。为了实现所提出的方法,K波段FMCW雷达实现了一个L形天线。
In this paper, a three-dimensional (3D)-subspace-based azimuth angle, elevation angle, and range estimation method with auto-pairing is proposed for frequency-modulated continuous waveform (FMCW) radar with an L-shaped array. The proposed method is designed to exploit the 3D shift-invariant structure of the stacked Hankel snapshot matrix for auto-paired azimuth angle, elevation angle, and range estimation. The effectiveness of the proposed method is verified through a variety of experiments conducted in a chamber. For the realization of the proposed method, K-band FMCW radar is implemented with an L-shaped antenna.
