摘要 为了在状态空间超分辨理论的框架下获得雷达目标散射点数目的估计,本文提出了一种基于状态空间理论的雷达高频区目标散射点数判定准则,该方法利用信号与噪声子空间的正交性质,搜索最优的散射点数目.理论分析与仿真试验均证明了该方法的正确性. For the purpose to accurately estimate the number of scatterers, a criterion based on SSM is presented to detect the optimal number of scatterers. The simulations prove the validity of the whole algorithm.
