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, the adaptive beam-forming (ADBF) algorithm is commonly used for sup-pressing the side-lobe interference. In view of the large computation of ADBF algorithm while the number of ar-ray elements being great, this paper proposes a method of lowering the dimensions using the sub-array space or beam space. By introducing partial adaptive array, the typical beam space ADBF (A-ADBF) algorithm is im-proved, and the improved one is not only of the advantages of the algorithm of beam space and sub-array space, but also more applicable for engineering implementation. Simulation results show that this proposed algorithm can form a null point effectively in the direction of interference.
