Research on Precision Control and Shape Keeping Technology of Light Radar Array

大型相控阵雷达已成为国防、天文、深空探测等领域亟需的大国重器,具有天线口径大、重达数百吨、高精度等技术特征。因大口径、大负载而导致的精度难以控制问题以及全生命周期保形问题成为大型相控阵雷达研制过程中需要首要解决的重大技术问题。本文介绍了大口径天线轻薄设计评估、全流程精度分配与控制、以及大口径天线测量标定与变形补偿等关键技术,为大型相控阵雷达精度控制与保形提供了解决方案,支撑我国系列重大战略装备成功研制。

The large phased array radar has become a great equipment in the fields of national defense, astronomy, deep space exploration and so on. It has the technical characteristics of large antenna diameter, weighing hundreds of tons and high precision. Due to the large aperture and heavy load, the precision is difficult to control and the whole life cycle shape keeping problem becomes major technical problems to be solved in the development of large phased array radar. This paper introduces the key technologies such as lightweight design evaluation of large aperture antenna, whole process precision distribution and control, measurement calibration and deformation compensation of large aperture antenna, which provides solutions for precision control and shape keeping of large phased array radar, and supports the successful development of a series of major strategic equipment in China.
