| 摘要: |
| 开展对局部最优检测器 (LOD)的研究有重要的理论和实际意义。本文建立了一种广义 LOD 模型和准则，据此导出几种典型信号的 LOD 结构,采用 Pitman 的渐近相对效能 (ARE)作指标研究了这些 LOD 的渐近性能；在广义 Gauss、Weibull 和对数正态分布的噪声模型中对上述 LOD 的 ARE 作数值计算，并及出相应的结论。 |

| Generalized Locally Optimum Detectors and their Asymptotic Performance |

| Abstract: |
| It is important to study the locally optimum detectors (LOD) both in theory and practice. In this paper a model and a criterion are proposed for the generalized LOD. On the basis of such criterion，the genevalized LOD structures are devived for detecting several typical signals in non-Gaussian noise，and the asymptotic relative efficiency (ARE) due to Pitman is used to evaluate their performance. Finally，numerical calculations are carried out for ARE of these LOD and some valuable conclusions are obtained. |
