新体制民用雷达与实时信息处理研究
New System Civil Radar and Real Time Information Processing

随着天线制造技术、超宽带技术、合成孔径技术和信息处理技术的发展，雷达的体积不断减小，探测精度和成像分辨率大大提升，雷达开始在民用领域中活跃起来，尤其是应用于穿透成像、微波遥感成像、滑坡监测和机场异物检测等领域的民用雷达发展十分迅速。为了让民用雷达在复杂的自然环境中具有更高、更稳定的性能，雷达信息处理技术一直在不断创新。本文介绍了民用雷达的新趋势和新技术，以及探墙雷达、微型SAR、边坡雷达和异物检测（Foreign object debris,FOD)雷达实时信息处理的关键问题和解决方案。
With the development of antenna manufacturing technology, ultra-wideband technology, synthetic aperture technology and signal processing technology, the radar volume is decreasing, and radar detection accuracy and imaging resolution are greatly improved. Furthermore, radar began to be active in the civilian field. New civil radars which are used in penetrating imaging, microwave remote sensing imaging, landslide monitoring and airport foreign object debris detection are developing rapidly. In order to make civil radars with higher and more stable performance in a complex natural environment, radar signal processing technology has been innovating. Here, we introduce the new trends and new technologies of civil radars, as well as the key issues and solutions of signal processing for the wall penetrating radar, the small SAR, the slope radar and the foreign object debris(FOD) radar.
