一、概况关于红外搜索跟踪系统与雷达,就其性能而言,多少年来就存在着争论。早在第二次世界大战初期,英国科学家就提出用红外系统代替雷达,限于当时红外技术的发展水平,没有取得成功。公正地说,两者各有优缺点,可以互相补充。雷达的优点是探测距离远,不大受大气和气象条件的影响,并能提供目标距离这个重要参数。红外搜索跟踪系统与雷达相比,有如下优点: (1)红外搜索跟踪系统不仅能够在妨碍雷达工作的主动干扰环境中使用,而且能够探 First, an overview About infrared search and tracking systems and radar, in terms of its performance, there have been controversies over the years. As early as the early World War II, British scientists proposed the use of infrared systems instead of radar, limited to the level of development of infrared technology at that time, did not succeed. To be fair, both have their own advantages and disadvantages and complement each other. The advantage of radar is the detection range is far from atmospheric and meteorological conditions, and can provide the target distance of this important parameter. Compared with the radar, the infrared search and tracking system has the following advantages: (1) The infrared search and tracking system can not only be used in an active interference environment that interferes with the radar work, but also capable of exploring
