说明：  首先介绍了低截获概率雷达发展状况，然后分析了低截获概率雷达的截获因 子，讨论了雷达各个参数对雷达低截获性能的影响和工程中各种措施对截获因子的影 响
(Digital beam forming is in digital signal processing methods established on the basis of a technology, it is widely used In radar, sonar, communication and electronic countermeasures, etc. Thesis in digital beamforming algorithm robustness, Moving target tracking digital beam, were studied)
