摘　　要：红外成像系统具备优秀的夜间可视能力,并且具备良好的抗干扰能力、识别伪装的能力,在军事领域的应用日益广泛。可见光成像系统易受光照强度的影响,无法在封闭空间或夜间等弱光条件下工作,而物体的红外辐射能量仅与物体温度和物质特性有关,所以红外成像不需要考虑光照强度,可以在全天候时段工作。红外目标检测可以应用单波段和多波段的方式进行探测,单波段探测由于目标信息有限,往往目标会存在小、弱、暗等问题,导致检测能力不理想,而多波段检测通过利用不同波段信息的冗余性、互补性,大幅度提高目标检测和识别的概率,提高识别伪装的能力。但双波段目标检测中存在很多技术难点,对红外小目标检测技术进行了分类,分析了技术难点,按不同的方法进行了总结描述。再对双波段目标检测技术进行了详细的描述,并选取了常见算法进行了性能比较和原理分析,突出了双波段目标检测的优势。Infrared imaging systems have excellent night visual ability,good anti-interference ability,and camouflage recognition ability,being widely used in the military field.The visible light imaging system is vulnerable to the impact of light intensity,and cannot work in closed space or at night under weak light conditions,while the infrared radiation energy of an object is only related to the temperature and material properties of the object,so infrared imaging does not need to consider the light intensity,and can work in all-weather time.Infrared target detection can be carried out in single-band and multi-band ways.Due to the limited target information,single-band detection often has problems such as the small,weak and dark targets,which will lead to unsatisfactory detection ability.However,multi-band detection greatly improves the probability of target detection and recognition,and improves the ability of recognition and camouflage by utilizing the redundancy and complementarity of information in different bands.However,there are many technical difficulties in dual-band target detection.First,the classification of infrared small target detection technology is carried out,and the technical difficulties are summarized and described according to different methods.Second,the dual-band target detection technology is described in detail,and some common algorithms are selected for performance comparison and principle analysis,highlighting the advantages of dual-band target detection.
