Based on the analysis of the scanning procedure of single-sampling and over-sampling systems,we proposed a novel scanning image simulation method. The target energy gathering,clutter suppression,and dim target detection of single and over-sampling systems were performed in 3 different scenes,mild-cloudy,severe-cloudy,and cirrus-cloudy.Analysis and experiments indicate that over-sampling system has better performance at target energy gathering,clutter suppression,and dim target detection.
