中文摘要： 精确制导能确保飞行器在复杂战场环境中精确命中目标乃至要害部位，其核心是精确导引和控制，而制导信息是导引系统给控制系统的指令，是实现精确制导的关键。因此本项目针对红外成像制导领域亟待解决的制导信息提取问题，研究单像素成像体制下的制导信息提取方法。研究红外图像的稀疏表示与观测矩阵，设计快速采样策略，采集含目标重要信息的稀疏信号；从采样的少量信号中以信号分析的角度进行目标识别与制导信息提取。这种"采样稀疏信号－提取有用信息"的方式突破了焦平面成像制导"采样整幅图像－图像处理－提取制导信息"的传统方式，在探测与采样阶段同步实现目标识别与制导信息提取。所提出的新型制导体系根据图像稀疏性有针对性地获取目标有效信息，增加重要性高的图像信息的采集与处理，能够克服传统焦平面阵器件的非均匀性，具有有用信息比例高、处理速度快等优势；对发展新型智能探测成像体制和制导信息提取方法具有重要的理论意义与应用参考价值。

英文摘要： Precision guidance ensures that the aircraft hits a target and key parts of the body with astounding accuracy in the complex battlefield environment. The core of precise guidance is the precisely seeker subsystem and control subsystem. The guidance information is the key technology of precise guide system, and is outputed to control system as an instruction by seeker system. Therefore, aim at guidance information extraction which is the problem to be solved urgently in infrared imaging guidance, this project will focuse on the extraction of guidance information based on the single-pixel imaging system. Firstly, we will study the sparse representation of the infrared image, and design the strategy of sampling the sparse signal fastly from the infrared image according to the measurement matrix. The sensing sparse signals are relatively few, and capture most of the target information which is important for the recognition.Then we will put an emphasis on target recoginition and guidance information extraction from the sensing relatively few sparse signal. The process of recoginition and extraction is similar to the process of signal sampling. The way of "sampling sparse signal - extracting useful information" will break out the traditional way of "sampling the whole image- processing image- extracting guidance info
