中文摘要:

      大功率工作的相控阵雷达电磁环境十分复杂,准确、高效的近场辐射分析方法是人员、设备安全保障的前提。文中以某相控阵雷达为例,提出了相控阵雷达近场辐射分析的方法。通过对相控阵阵面和周围环境的简化建模,仿真得到需求位置的电场强度。然后在实际位置进行功率测试,以判断计算与实测的误差。仿真结果与实测结果吻合性很好,证实了所提出的近场辐射分析方法的准确性和有效性。这为相控阵雷达电磁辐射问题提供了高效的分析方法,具有重要的意义。

英文摘要:

      The electromagnetic environment of high-power phased array radar is very complex. Accurate and efficient nearfield radiation analysis method is the premise of personnel and equipment security. By taking phased array radar as an example,this paper presents a method of near-field radiation analysis for phased array radar. The electric field intensity of the demand location is obtained by simulating the simplified modeling of the phased array plane and the surrounding environment. Then, the power is tested in actual position to judge the error between calculation and measurement. The simulation results are in good agreement with the measured ones, which proves the accuracy and effectiveness of the proposed near-field radiation analysis method. This provides an efficient analysis method for electromagnetic radiation of phased array radar, which is of great significance.
