摘　　要：数字波束形成(DBF)技术在相控阵雷达中已广泛使用,它是雷达空域抗干扰的重要技术。在传统的波束形成中存在干扰处的零陷较窄,干扰功率不稳定导致干扰零陷较浅的情况。旨在一体化解决上述两个问题,分析了零陷展宽和零陷加深的基本原理,推导了计算公式并进行了仿真;将两者综合考虑进行了推导和仿真,结果表明,进行零陷加宽和加深一体化设计,可以综合两者的优点,大大增强波束在干扰方向的稳健性,提高了雷达的抗干扰性能。Digital beam forming （DBF） technology is widely used in phased array radar, which is an important technology of anti-interference in airspace for radar. There is null narrow in the interference of conventional adaptive beam former, and null shallow caused by interference pow- er unsteady. In order to solve above two problems compositely, the basic principle of the zero in broadening and deepen is analyzed, and the simulation calculation formula is deduced. Both derivation and simulation are proposed, the results show that zero in widening and deepening in- tegration design can greatly enhance the beam robustness in direction of interference, improve performance of phased array radar on anti-jamming.
