【摘要】 本文基于自适应旁瓣控制算法中存在的参数调整困难、收敛速度慢、精度差的问题,提出了一种改进的控制算法。该算法具有收敛速度快、精度高的特点,另外,使用该算法无需调整参数,只需给出期望的旁瓣级和允许的误差范围即可求出需要的最优权向量。由于该算法可用于不同的阵形,因而具有很强的通用性。更多还原

【Abstract】 In adaptive sidelobe conrol algorithms,the paramethers are difficult to be adjusted,and the rate of convergence is slow,at the same time the precision is low.An inproved sidelobe control algorithm is presented to solve this proplem.The convergence rate of the algorithm proposed is faster,and the precision is higher than the old one.In addition there is no need to adjust any parameters in the algorithm.The optimal weights can be caculated whenever the expected sidelobe level and the permitted error range are given.The algorithm is versatile because it can be used in arrays of any shape.更多还原
