查询词典 extracting

Proposed a DHCM for extracting targets′tracks from 3-Dimensional (3D) data, and made a detailed performance analysis on the DHCM′s detection probability, noise rejection capability and computation burdens. Theoretical analyses indicate that the DHCM has a high noise rejection capability, and has neural network structure, hence has stronger adaptivity and robust to noise properties.

理论分析表明，该方法具有较高的噪声抑制能力，并具有神经网计算结构，因而，对噪声特性具有较强的自适应能力和稳健性。3）基于有向高阶相关的方法，提出了一种用于在红外噪声中检测、跟踪低信噪比点目标的方案。
