本文提出了一种在相控阵雷达中利用总体最小二乘 (TLS)估计进行目标角度截获 ,提取目标角度信息的方法 .该方法不仅考虑了线性模型中观测向量的噪声扰动 ,而且考虑了数据矩阵中的噪声扰动 ,采用TLS估计的角度截获方法可以使包括观测向量误差和数据矩阵误差在内的误差矩阵达到Frobenius范数的最小值 . In this paper, we propose a method to extract target angle information by using total least square (TLS) estimation in phased array radar, which not only considers the noise disturbance of observation vector in the linear model, but also considers the data The noise perturbation in the matrix, the angle capture method using TLS estimation, minimizes the error matrix including the observed vector error and the data matrix error to the Frobenius norm.
