摘要：

波导缝隙阵天线具有结构紧凑、质量轻、性能好等优点，常被用于机载或弹载雷达等多种设备。随机振动是雷达工作时的主要载荷形式，振动引起的天线变形会对天线增益产生一定影响。目前用传统方法计算随机振动对天线增益影响的过程非常复杂，且计算量很大，为此提出一种利用位移响应的均方根来计算随机振动对天线增益影响的等效方法。假设随机振动是满足均值为零的正态分布的随机过程，利用各个节点的完全相关性可生成多组样本，首先利用传统方法和等效方法分别计算得到随机振动下天线增益的均方根，然后利用泰勒展开式推导等效方法的适用条件，最后以宽边波导缝隙阵天线为例，通过数值仿真和实验验证等效方法的有效性。研究表明：等效方法误差小于0.1 dB，该方法在满足一定条件时，能够快速计算随机振动对天线增益的影响。该等效算法可大大提高计算效率、节约计算时间，同时计算结果具有重要工程意义，为天线设计人员提供参考。

Abstract:

Slotted waveguide array antenna has the advantages of compact structure,light weight, good performance and so on,and it is often used in airborne radar or missile borne radar.The ran-dom vibration is the main load form of radar and causes the antenna distorted,which affects the radiation gain.At present,the traditional process for calculating the effect of random vibration on the antenna gain is very complicated and consumes more computation time and memory.An e-quivalent method for calculating the effect of random vibration on the antenna gain was proposed by using the root mean square values of the distorted displacement response.It was assumed that the random vibration load was a stationary process of a normal distribution,and the average value of the load was zero.Multiple samples were generated based on the complete correlation between each node.Firstly,the root mean square values of the gains were obtained by the traditional method and the equivalent method.Then,the applicable condition of the equivalent method was deduced by Taylor expansion.Lastly,taking the broad-wall longitudinal slotted arrays in rectan-gular waveguides as an example,the validation of the presented approach was confirmed by using simulation and experiment,and the maximal calculation error was less than 0.1 dB.The study showed that the effect of random vibration on the gain of the antenna could be calculated quickly under certain conditions.This equivalent method greatly improves the computational efficiency and saves computation time.The result has great significance of engineering,and provides a ref-erence to antenna designers.
