IR target recognition based on invariant sequential spectral angle
摘要
Abstract
An infrared target recognition method based on the invariance of spectral angle in time sequence is proposed to recognize spatial targets and balloon decoys.The difference between spatial targets and balloon decoys on the time-varying characteristics of temperature is gained.In order to reflect the time-varying characteristic essence of target measurement power temperature and to eliminate the time-varying coupling influence of the sensor,target distance and the equivalent projective area on the power measurement,the sequential spectral angle is presented as a sequence varying measure of the spectral vector.The measure can depict the sequence varying of the spectral curve and unti-demonstrate the time-varying characteristics of object temperature by the measurement,and it is regarded as an efficiency criterion of clustering recognition concept between targets and decoys.Simulation result shows that this method could effectively recognize spatial targets and balloon decoys.It provides a new mechanism for space target recognition by merging the sequential spectral characteristics.关键词
