一体化侦测阵列天线技术研究

本文在一种宽带偶极子单元天线的基础上，对由单元天线组成的常规侦测阵列进行改进设计，通过组阵方式实现了一种新颖的一体化侦测阵列天线。文章运用HFSS 电磁仿真软件结合干涉仪测向原理分别对两种侦测阵列进行性能比较。结果表明，新颖的一体化阵列实现了既包括常规侦测阵列的功能，又利用其组阵后的波束形成及其控制灵活等特 点，较单元天线实现更高的天线增益，这对提高系统的灵敏度和多功能性有很大帮助，比较适合应用于宽带一体化侦测系统。

Research of the Integrated Survey and Direction FindingArray Antennas Technology

A routine direction finding array antenna composed of element antennas is improved on the basis of widebandwidth element antenna, and a kind of new integrative direction finding antenna is realized by the way of changing arraystructure form. The performance of two sorts of direction finding arrays is compared by electromagnetic simulation softwareHFSS and interferometer direction finding principle. The research indicates that the new integrative array not only includes thefunction of routine direction fnder array, but also has the characteristic of wave beam forming, flexible control and highantenna gain than the routine array. The merits of the new array can improve system sensitive performance and provide systemwith more function. The new integrative array is very fit for wide bandwidth integrative direction finding system.
