摘要: 以分形理论为基础,为红外目标识别建立了一种新的数学模型。将红外目标功率谱曲线离散化成数据序列,结合数据处理的方法,提取出具有对具体目标基本不变的特征量——能量维,这是分形维的具体表现形式。实验表明这种数学模型是可行的,并且具有较高的识别能力和可靠性。

Abstract: A new model has been built for infrared target recognition based on the fractal theory.丄 he power spectrum density curves of infrared targets are dispersed into data series. By means of data-processing, the essentially constant characteristics of con?crete targets, namely the power dimension, which is the concrete form of expression of the fractal dimension, is drawn. Experiments have shown that this model is feasible and is of high recognition ability and reliability.
