一种小孔径高精度测向系统

System for DF with short base-line and high performance

传统的干涉仪测向等手段在天线布阵时基线尺寸受来波波长限制,无法做到小型化、便携式,其应用受到严重制约。本文研制出一种可不受来波波长限制的测向系统,利用辐射源来波的幅度和相位特性进行矢量合成,在极小的天线尺寸下获得较高的测向精度及灵敏度,能够更好的满足各类不同的应用场景。试验结果表明该系统能够在相同尺寸下获得相较于干涉仪测向更高的测向精度。

Traditional DF method is limited by wave length in the size of the antenna array which can not be miniaturization and portable. This paper develop a system which can break through the limitation of length wave, Get high performance with Utilize the phase and magnitude, can satisfy different scenario. Finally this paper list the DF result of the system.The Experiments show that this system can get better results than Traditional DF method.
