现代水面舰艇上相控阵雷达的应用越来越广,发射功率愈来愈大,频谱的覆盖范围也越来越宽,其射频能量对甲板或周边环境的人、军械、燃油等都有潜在的危害,电磁辐射对维护操作人员和甲板作业的影响已经不能忽视。为了减轻大功率雷达辐射对人体影响,分析了相关军用标准,研究了相位加权方法在相控阵雷达中的应用,提出了减少甲板作业区域的电磁辐射强度改善方法,为舰载大功率雷达设计提供了主要技术途径。

Phased array radar is the direction in the use of the advanced naval vessels. The output power of radar is increased consequently,and the influence of radar electromagnetic wave on human, ordance and fuel is also gradually known to the world. For reducing the hurt to the operator when he is working on the deck, the judgment standards are analyzed, and the simulation model is established, the usement of antenna phase weighting method in phase array radar is studied. In the end, the technique of how to decrease the electromagnetic power density for design the ship-borne radar is given.
