【Abstract】 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-Least-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.更多还原
