| 摘 要： | 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一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.

| Abstract: | In digital array radar, the adaptive beam-forming （ADBF） algorithm is commonly used for suppressingthe side-lobe interference. In view of the large computation of ADBF algorithm while the number of arrayelements being great, this paper proposes a method of lowering the dimensions using the sub-array space orbeam space. By introducing partial adaptive array, the typical beam space ADBF （A-ADBF） algorithm is improved,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 algorithmcan form a null point effectively in the direction of interference. |
