| 摘 要： | 分析了单采样和过采样两种扫描探测体制的成像原理,并建立了扫描图像仿真模型。在不同云层杂波场景下从目标能量收集、背景杂波抑制和弱小目标检测三个方面对单采样和过采样扫描图像进行了对比分析。理论分析和仿真结果表明：过采样扫描探测体制更有利于收集目标能量,杂波抑制能力较优,对弱小目标的探测能力更强。

| Abstract: | Based on the analysis of the scanning procedure of Single-Sampling and Over-Sampling systems, we proposed a novel scanning image simulation method, and we prepared the performance of target energy gathering, clutter suppression, and dim target detection of Single and Over-Sampling systems in 3 different scenes, that was mild-cloudy, severe-cloudy, and cirrus- cloudy scenes. Analysis and experiments indicate that Over-Sampling system has better performance at target energy gathering, clutter suppressing, and dim target detecting. |
