Phased-array antenna installation parameter calibration method based on gradient descent algorithm

The invention discloses a phased-array antenna installation parameter calibration method based on a gradient descent algorithm, and the method comprises the steps: obtaining a mean square error between a coordinate obtained through calculation at a calibration point and an actual coordinate according to a mathematical model of a phased-array antenna; and adjusting antenna installation parameters used in the mathematical model by using a gradient descent method, so the mean square error reaches the minimum, and at the moment, the optimal installation parameter value can be obtained. The method can be realized through an automatic program, a plurality of calibration points are selected on a construction site, the OBU is placed on the calibration points to respectively trade with the antenna, the installation parameters of the antenna can be calculated by using an automatic tool, and the whole process is convenient to operate and easy to use on the construction site. 本发明公开了一种基于梯度下降算法的相控阵天线安装参数校准的方法，根据相控阵天线的数学模型，
