不论在军事还是民用领域，目标识别都是现代雷达的重要功能，也是雷达智能化的基础。由于复杂的电磁环境，目前的雷达目标识别能力往往不能满足要求。雷达探测数据维度的增加可以极大的提高雷达性能，并为雷达目标识别提供更丰富的目标特征。最近的研究显示，在经典波（光波和微波）系统中能够构造出与量子关联相对应的关联关系，也就是超越Bell不等式的经典波关联。众所周知，在量子信息领域，利用量子关联可以实现超精密的目标识别。我们期待在经典系统中，利用与量子关联对应的经典关联也能达到类似的效果。本项目研究的主要内容就是将这种新的经典波关联方法引入到微波雷达系统中，建立相关的微波关联理论，设计雷达测量新体制，并对目标关联信息进行探测，以实现雷达在测量精度，抗干扰能力和目标识别能力等方面的突破。本项目在量子关联的启发下，将关联维度引入到传统雷达，可为现役雷达和下一代雷达提供一个新的方向。

Target recognition is an important function for modern radars in both military and civilian fields, which is also the basis of radar intelligence. However, the complexity of the electromagnetic environment limits the performance of the related methods. Studies have shown that a new detecting dimension could greatly improve radar performance and obtain more target features for recognition. Recent studies show that a correlation which shares the same inseparability with quantum correlation that surpasses Bell’s inequality could be constructed in a classical wave(optic wave and microwave) system. It is known that in quantum information field, quantum correlation can achieve ultra-precise target recognition. We expect that classical correlations can achieve similar results in classical systems. Therefore, this project is to introduce the classical wave correlation into microwave radar systems, establish related mircrowave correlation detection theory and design a new radar measurement system. By detecting the correlation information of the target, we tend to make breakthroughs in high resolution measurement, anti-intergerence and target recognition. Inspired by quantum correlation, this project introduces the correlation dimension into traditional radar, which provides a new direction for current and next-generation radar.
