从20世纪70年代开始,浮空器这种轻于空气的古老飞行器正式用于军事侦察。其实早在50年代中期,美国海军就已经在ZPG-2W/-3W 计划中首次将雷达安装在浮空器上。随着时间的推移,将雷达安装在浮空器上变得越来越普遍了。安装有雷达的浮空器和飞艇(带有动力装置) 开始在空中预警、本土防御以及缉毒、非法移民控制、专属经济区监视等军事及准军事任务中发挥越来越重要的作用。 Beginning in the 1970s, aerostats, the lighter-than-air ancient aircraft, were officially used for military reconnaissance. In fact, as early as the mid-1950s, the U.S. Navy had already installed the radar on the aerostat for the first time in the ZPG-2W / -3W program. Over time, it has become more and more common to mount radars on aerostats. Radar-mounted aerostats and airships (with power units) are beginning to play an increasingly important role in military and paramilitary tasks, such as aerial warnings, indigenous defense and anti-narcotics, illegal immigration control, and exclusive economic zone surveillance.
