摘　　要：本文在把阵元间幅相不一致性归结为阵元方向图畸变基础上 ,提出利用海杂波作为定标源对方向图进行拟合的几种方法 .文中详细叙述了利用最小二乘法及总体最小二乘法对方向图进行拟合的具体方法 .模拟结果表明总体最小二乘法是几种方法中的最优方法 .The near field scattering of the complex metal structures in the vicinity of an antenna array will cause serious distortion of the antenna array pattern. A scheme utilizing the broadened first-order Bragg lines to compensate the distortion of the antenna array pattern is presented and the Total-Lease-Square (TLS) technique used to estimate the element error-response pattern is described. The result of simulation to the error-response pattern of the antenna array shows that the TLS method is available and optimal in the estimation of the antenna array pattern in HF ship-born over-the-horizon radar environment.
