| 摘 要： | 针对在冲击噪声条件下基于高斯噪声模型的目标检测方法性能退化的缺点,提出了一种新的引信目标方位估计方法。该方法引入α稳定分布模型对冲击噪声建模,通过对引信阵列天线接收信号共变矩阵的特征分解估计噪声子空间,再依据最小范数算法实现了对目标方位的估计。计算机仿真实验证明了所提出新方法的有效性。

| Abstract: | Based on the weakness of the capability degeneration for target detection under the condition of impulse noise,a new DOA estimation method is presented.Firstly,the α stable distribution is introduced to construct non-Gaussian noise model.Then,the noise subspace is estimated by the eigen-decomposition of covariation matrices of fuse antenna receiving signal.Finally,the DOA estimation is carried out by min-norm(MNM) method.The efficiency of proposed methods is verified by the simulation results of the computer. |
