摘　　要：分析了数字阵列雷达在空域抗有源干扰方面的优势,提出了一种适用于地面数字阵列雷达系统的综合抗干扰方法,该方法基于同时接收数字多波束的处理架构,能够在抗干扰的同时改善对低空飞行目标的测角精度。文中结合外场试验结果和实测数据进行了验证分析,还从现代雷达电子战的角度对数字阵列雷达的空域抗干扰的局限性进行了分析,以期望对新体制数字阵列雷达在抗干扰方面的优势和面临的挑战有一个更加全面的认识。The advantages of spatial ECCM performance of digital array radar （ DAR） are discussed. For practical consideration, a novel ECCM technique for ground based DAR is proposed. The novel technique is based on architecture of the multiple simultane-ously DBF, which can improve the performance of the ECCM as well as the angle accuracy of the low-flying targets. The perform-ance of the novel method is evaluated using measured data recorded by an experimental 3D DBF phased array radar. At the same time, the limitations of spatial ECCM performance of DAR are also discussed in this paper. It is believed that the research and the discussion in this paper would be helpful for understanding the development of the ECCM and the challenge of the DAR.
