舰载大型相控阵天线是一种重要的通信和雷达设备，其性能直接影响舰船的通信和侦察能力。为了准确地评估这种天线的性能，需要进行电磁仿真计算。本文首先对大型相控阵雷达的工作原理进行介绍，建立相控阵雷达的目标检测模型，针对大型相控阵天线的仿真计算，提出一种基于矩量法（MOM）的舰载大型相控阵天线的仿真计算方法。该方法利用MOM方法对天线的辐射特性进行计算，能够有效评估舰载大型相控阵天线的性能，为天线设计和优化提供重要的参考依据。
Shipborne large phased array antenna is an important communication and radar equipment, its performance directly affects the ship's communication and reconnaissance capabilities. In order to accurately evaluate the performance of this antenna, electromagnetic simulation calculation is needed. In this paper, the working principle of large-scale phased array radar is introduced, the target detection model of phased array radar is established, and a simulation calculation method of shipborne large-scale phased array antenna based on the method of moment (MOM) is proposed. The MOM method is used to calculate the radiation characteristics of the antenna. The results show that the method can effectively evaluate the performance of shipborne large phased array antennas, and provide an important reference for antenna design and optimization.
