说明：  本文针对基于高斯分布的非线性滤波问题，开发并分析了实时和精确滤波器。我们提出了高斯滤波器的系统公式，并开发了高效和精确的数值积分。我们还讨论了混合高斯滤波器，其中条件概率密度由高斯分布之和近似。数值试验表明，新的滤波器在不增加额外费用的情况下显著地改善了扩展卡尔曼滤波器，并且新的高斯和滤波器具有接近最优的性能(In this paper we develop and analyze real-time and ac- curate filters for nonlinear filtering problems based on the Gaussian distributions. We present the systematic formulation of Gaussian filters and develop efficient and accurate numerical integration of the proposed filter. We also discuss the mixed Gaussian filters in which the conditional probability density is approximated by the sum of Gaussian distributions. Our numerical testings demonstrate that new filters significantly improve the extended Kalman filter with no additional cost and the new Gaussian sum filter .has a nearly optimal perfor- mance.)

在舰船有限的布置空间内，近百副大功率和高敏感性用频设备的天线密集布置，由各种大功率源产生的辐射近场强电磁环境，不仅对舰面武器弹药作业、舰载机加油作业和人员安全构成了严峻威胁，且极易造成对各种舰载和机载敏感设备的电磁干扰。全波计算方法对运算平台要求高，对于舰船超电大尺寸结构，即使采用高端的计算机，完成一次计算也要消耗大量的时间和资源，并会遭遇方程组迭代不收敛等问题，无法满足设计精度和工程需求。随着射频集成技术的发展，新型舰船上广泛采用平面相控阵天线。相控阵天线工作频率至Ku以上波段、阵元数目庞大、阵元是金属-介质复合结构，使预测舰船微波强电磁环境、进行舰载设备间电磁干扰分析具有极大难度。
