在数字阵列雷达中,自适应波束形成(ADBF)算法常被用来抑制副瓣干扰.针对当阵元数较多时ADBF算法运算量很大问题,采用子阵空间或波束空间的方法进行降维处理.通过引入部分自适应阵方法对经典波束空间自适应波束形成(A-ADBF)算法进行了改进,改进后的算法不仅具备波束空间和子阵空间算法的优点,而且更加适合工程实现.仿真结果表明,该算法能有效地在干扰方向形成零点. In digital array radar, adaptive beamforming (ADBF) algorithm is often used to suppress the sidelobe interference.For ADBF algorithm with large number of array elements, the problem of large amount of computation is solved by using sub-array space or beam space dimensionality reduction (A-ADBF) algorithm is improved by introducing some adaptive matrix method.The improved algorithm not only has the advantages of beam space and sub-array space algorithm, but also more suitable for engineering implementation.The simulation results It shows that this algorithm can effectively form zero point in the interference direction.
