| 摘 要： | 对于红外扫描有效载荷等光电探测系统,瞬时视场的减小(提高分辨率)对抑制背景杂波、提高检测概率和降低虚警率具有重要意义。过采样技术一直是提高仪器成像分辨率时的研究热点。针对点目标探测系统,对常规采样和过采样两种采样体制进行了对比分析。结果表明,在响应的标准差、平均响应和超出率方面,过采样系统具有明显优势。

| Abstract: | For optoelectronic detection systems such as an infrared scanning payload, the reduction of the Instantaneous Field of View (IFOV) is important for background
cluster suppression, detection probability improvement and false alarm rate decreasing. An oversampling technique is always the research hotspot for the improvement of the imaging resolution of an imaging instrument. In view of a point target detection system, the normal sampling and oversampling techniques are compared with each other. The result shows that the oversampling technique has its obvious advantages in the respects of standard response deviation, average response and PEE. |
