摘要
在电子战测向系统中,天线性能的优劣是决定整个测向系统技术指标好坏的关键。在宽频带内,天线方向图要满足整个测向系统的要求,这有很大难度。通过对几种工作频带在3∶1以上的天线的分析,得出在比幅测向系统中天线单元比较好的解决方案。
In direction-finding（DF） system of electronic warfare（EW）,antenna performance is the key to decide technical index of the whole direction finding system. In the wide band, the antenna pattern should satisfy the requirements of total DF system,which is very difficult. A better solution project of antenna cell in amplitude-comparison DF system is obtained through the analysis of sev- eral antennas that the work frequency band is above 3： 1.
