| 随着现代电磁环境越来越复杂，对空域多波束形成的要求越来越高，而数字阵列雷达有着波形灵活设计、多波束形成便捷可控等优点。但在复杂的战场环境下数字阵列天线如何在强干扰环境下实现深零陷抑制，或者在一定宽度的角度范围实现零陷抑制的同时，保持阵列天线的发射功率是一个值得研究的问题。本文基于数字阵列雷达开展其多样多波束形成方法的研究工作，通过对加权幅度进行约束，减轻了各个天线上的加权幅度的起伏特性，在保持性能的同时获得了更高的发射效率。 |

| Abstract: |
| As the modern electromagnetic environment becomes more complex, the demand for spatial multi-beamforming is growing. The digital array radar （DAR） exhibits advantages such as flexible waveform design and controllable multi-beam generation. However, in the complex battlefield environments, how to achieve deep null suppression against strong interferences, or implement null suppression in a certain width of the angle range while maintaining transmitting power is a challenging problem. In this paper, based on the digital array radar, the research work of its diverse multi-beamforming method is carried out. By constraining the weighted amplitude, the fluctuation characteristics of the weighted amplitude on each antenna are reduced, and higher transmission efficiency is obtained while maintaining performance. |
