摘　　要：地空和空空导弹是直升机在战场上的主要威胁。及时探测识别来袭导弹并实施干扰是提升直升机战场生存能力的重要手段。紫外告警由于信号处理简单、低虚警、无需扫描和制冷、被动探测等优点,得到了广泛的研究和应用。它是目前装备量最大的导弹告警系统之一。但在真实战场环境中各种随机干扰源经常会引起紫外告警系统虚警,这会降低告警可信度。所以,对干扰源的处理是紫外告警系统必须且重要的组成部分。目前,所有的研究集中在地面干扰源和散射噪声干扰源。但真实战场中,载机干扰源如机载导弹也是造成告警虚警的一大原因。论文首次提出了载机干扰源的概念,并从诱饵整个投放过程给出了识别方法。最后,论文用该方法处理载机干扰源视频以验证方法的有效性。The air-to-air and surface-to-surface missiles are the main threat to helicopter on the battlefield. So it is an important means to improve helicopter battlefield viability by detecting and recognizing missile and interfering. Due to simple signal processing,low false alarm,no scanning,no refrigeration and passive detection,the UV alarm has been diffusely researched and applied. It is one of the most equipped missile alarming system. But in the truly battlefield environment various random interference sources always bring the system false alarm,reduce alarm confidence level. So,it is an significant process to deal with interference sources in UV alarm system. Currently,all the researches mainly focus on ground interference source and scattering noise interference source. But in the truly battlefield,aircraft interference such as aircraft bait is also the main reason for false alarm. The article firstly proposes the concept called aircraft interference,and shows a recognition method based on the whole bait lunch process. Finally,for proving the method effectiveness,aircraft interference video is dealt by the method.
