48357 外辐射源雷达面临严重的多径杂波问题,传统的梯度自适应格型(gradient adaptive lattice,GAL)滤波是一种有效的杂波抑制算法,但该算法需要根据经验合理设置步长参数,收敛速率慢,在抑制杂波的同时会造成处理距离元内的目标回波被部分相消。 Outside source radar facing serious multipath clutter problem, traditional gradient adaptive lattice (gradient adaptive lattice, GAL) filtering clutter suppression algorithm is an effective, but the algorithm needs according to the experience setting up reasonable step parameters, slow convergence rate, while suppress clutter will cause processing from yuan within the target echo is part of the cancellation.
48358 基于传统的GAL滤波提出了一种改进的GAL算法及其前后向预测误差的归一化形式,该算法通过最小化前向和后向预测误差的均方值估计反射系数,并通过最小化多重回归滤波的均方误差估计其权系数。 Based on the traditional GAL filter before and after the proposed an improved algorithm of GAL and its to the normalized form of prediction error, the algorithm by minimizing the forward and backward prediction error of the mean square value estimate reflection coefficient, and by minimizing the mean square error estimation of the multiple regression filter weight coefficient.
48359 相对传统的算法而言,改进的算法不需设置步长参数、收敛速率快、对处理距离元内的目标回波基本没有影响。 Compared with the traditional algorithm, the improved algorithm does not need to set the step size parameter, fast convergence rate, to deal with distance yuan had little influence upon the target echo.
