摘　　要：提出了一种高分辨阵列测向的全局优化自校正算法。对在模型失配的情况下,利用投影矩阵所形成的谱估计矩阵,同时对信号的到达方向及未知的模型误差参数进行估计,并利用退火模拟算法保证算法能收敛于全局最优解。为简单起见,文中仅考虑阵元的增益及相位误差参数。This paper proposes a global optimizatoim algorithm for calibrating array errors. The spectral-estimation matrix is formed from the projection matrix to estimate the direction of arrival and unknown error's parameters simultaneously,and the simulation annealing is utilized to guarantee that algorithm converges to the global minimum.For the simplicity the algorithm presented here considers gain and phase errors only.
