| 摘 要： | 基于幅度比较单脉冲方法的测角局限性,采用先进的阵列超分辨测向技术MUSIC算法,对处于同一距离门和频率门的2个目标,在纯噪声背景和杂波背景下进行了波达方向(DOA)估计,对不同的信噪比和目标进入角度,仿真了目标的分辨情况并计算了DOA角度估计的精度,证明了机载雷达方位超分辨角度估计可以较好地实现落入清晰区或者副瓣杂波区目标的角度分辨与精度估计,但是对目标的信噪比和进入角度有一定的要求.

| Abstract: | Because of shortcoming of monopulse angle measurement,the two or more closed targets in the same range gate and in the same frequency gate must be distinguished by super-resolutuon direction estimation.In this paper,the simluator of super-resolutuon direction estimation of digital array radar in clutter is studied.The SNR and angle of targets are varied,and the paper gives estimation of the space spectrum and DOA angle.It is shown that the super-resolutuon direction estimation has some useful information on... |
