基于模糊信息论的空中目标识别模型研究

Research on Aerial Target Identification Model Based on Fuzzy Information Theory

空中目标识别是防空作战辅助决策的关键环节之一。针对目标识别中不确定信息,建立基于模糊信息论的空中目标识别模型。该模型利用模糊信息论中的模糊数,基于贴近度的模糊模式识别对待识空中目标进行初步识别,同时为解决不确定信息本身对目标识别结果稳定性的影响,采用模糊信息熵对目标识别结果修正,从而进一步提高了空中目标识别结果的稳定性和可信度。

The efficiency of aerial target identification is one of key process in the combat decision-aid for anti-air. Aiming at settling the problem of uncertain information, the aerial target identification model is established on the theory of fuzzy information and the aerial target is identified by using fuzzy number and fuzzy mode identification on the fuzzy degree similarity. At the same time, aiming at reducing the affect caused by uncertain information to the result, the fuzzy information entropy is used to modify the result. So the stability and reliability of the result is advanced.
