上个世纪四十年代初,雷达技术的改进和应用催生了一项新的技术。雷达发射信号,遇物体反射,通过对反射信号的识别,可以判断物体的距离和大小。二战期间,这项技术被英国军方应用到了空军战场上,在战斗中用以区分己方与敌方的飞机。这项技术的延伸发展就形成了今天的射频识别技术(Radio Frequency Identification,简称RFID)。1948年,美国的一位无线电工程师哈里·斯托克曼(Harry Stockman)奠
The early forties of last century, radar technology improvements and applications gave birth to a new technology. Radar signal transmission, in case of object reflection, through the reflection of the signal identification, you can determine the distance and size of the object. During World War II, the technology was applied to the Air Force battlefield by the British military, in the battle to distinguish one’s own and the enemy’s aircraft. The extension of this technology forms today’s Radio Frequency Identification (RFID). In 1948, Harry Stockman, a U.S. radio engineer, was founded
