摘　　要：本文首先对二维相控阵雷达坐标转换及坐标旋转进行了分析,然后在正旋空间进行波束排布和波束划分的研究,在阵面坐标系下进行配相,在雷达站球坐标系下分析波束分布及展宽。通过仿真验证了相控阵雷达空间扫描特点,这对雷达波束空间设计提供了参考。Firstly,the coordinate transformation and coordinate rotation of two-dimensional phased array radar were analyzed.Then the beam arrangement and the beam position determination were studied in the forward rotation space.Phase matching was performed in the array coordinate system,and the beam distribution and broadening in radar station spherical coordinate system were also analyzed.Space scanning characteristics of phased array radar was validated by stimulated tests,which provides a reference for radar beam space design.
