早在三十年代中期,几乎同时在世界好几个国家中独立地发明了雷达。在第二次世界大战期间,雷达由于其特殊用途而得到了飞快的发展。之后的几十年中,雷达不论在性能上还是在应用方面都变得非常成熟,成为独立的专业。本文将对现代雷达发展五十年的要点作一简明的历史回顾,随后提出当今引人注意的动向,最后给出29幅八十年代雷达的外貌图。 As early as the mid-1930s, radar was independently invented in several countries of the world at about the same time. During World War II, radar was rapidly developed due to its special purpose. After decades, the radar has become very independent in terms of performance and application. This article will give a concise historical review of the key points of the development of modern radar over the past 50 years, and then raise the current trend of attention. Finally, we will give a look of the appearance of 29 80-year-old radars.
