摘要

摘要: 高分辨波达方向(DOA)估计是地基/空基预警雷达实现主波束内多目标精细跟踪需要解决的关键问题。针对上述问题，该文提出一种波束-多普勒酉ESPRIT多目标DOA估计算法。该方法首先通过时域平滑技术构造多个快拍。然后采用中心共轭对称傅里叶变换矩阵将数据变换至波束-多普勒域，同时保留旋转不变结构。最后采用实值ESPRIT算法估计目标的DOA。所提方法充分利用了信号的时域信息来改善空域参数估计性能，同时具有较低的计算复杂度。实验结果证明了所提方法的有效性。

Abstract: High-resolution Direction Of Arrival (DOA) estimation is a critical issue for mainbeam multi-target tracking in ground-based or airborne early warning radar system. A Beam-Doppler Unitary ESPRIT (BD- UESPRIT) algorithm is proposed to deal with this problem. Firstly, multiple snapshots without spatial aperture loss are obtained using the technique of time-smoothing. Then the conjugate centrosymmetric Discrete Fourier Transform (DFT) matrix is used to transform the extracted data into beam-Doppler domain. Finally, the rotational invariance property of the space-time beam is exploited to estimate DOA. Since the proposed algorithm takes full advantage of temporal information and is implemented in low-dimensional beamspace, the DOA estimation accuracy can be improved greatly with dramatically reduced computational complexity. Numerical examples are given to verify the effectiveness of the proposed algorithm.
