摘要
研究了红外目标与诱饵在成像特性上的差异,指出动态特性是辨别真伪的主要特征.在点目标阶段,以目标成像灰度随时间变化的快慢作为灰度时间序列特征,并采用多分辨分析、时频分析等多种方法进行目标与诱饵的识别,给出了仿真试验结果.
Abstract
The infrared imaging characteristic difference between target and decoy is studied. It is pointed out that dynamic character is the main feature to distinguish target and decoy. At the stage of dot target, the variation magnitude of object's gray-scale intensity is regarded as the time sequence feature. Some methods such as multiresolution analysis and time-frequency analysis are adopted to identify target and decoy. The simulation result is given.
