雷达是现代军民航主要的空域监视设备,几十年来发展迅猛,技术日臻完善。随着中国经济的快速发展,飞行器数量猛增,“天高任鸟飞”的时代一去不返,提高空域利用率已迫在眉睫。鉴于单个雷达作用距离有限,组建雷达监控网, 实现航路及国土覆盖,是目前解决上述难题的主流技术。我国在成功实现京广、京沪两条航路的雷达覆 Radar is the main airspace surveillance equipment of modern military and civil aviation, which has developed rapidly in recent decades and its technology is improving day by day. With the rapid development of China’s economy, the number of aircraft has soared, and the era of “flying high as a bird” has never seen. It is imminent to improve the utilization of airspace. In view of the limited range of a single radar, the formation of radar monitoring network to achieve the route and land cover, is currently the main technology to solve these problems. Our country is successfully implementing the radar coverage of the two routes of Beijing-Guangzhou and Beijing-Shanghai
