摘要
四比幅测向技术常用于机载定位设备,通过测量、比较不同方向接收到的信号幅度来确定辐射源的大致位置。基于此,阐述比幅测向理论,提出通过软件控制信号源将信号注入待测设备的方式进行测向的方法。相较于传统的暗室测向方法,该方法能显著提高生产效率,节约暗室建设成本。
Four-amplitude comparison direction finding technology is often used in airborne positioning equipment to determine the approximate position of the radiation source by measuring and comparing the signal amplitude received in different directions.Based on this,this paper expounds the theory of amplitude comparison and direction finding,and proposes a method of direction finding by injecting signals into the equipment to be tested through software control signal source.Compared with the traditional darkroom direction finding method,this method can significantly improve the production efficiency and save the construction cost of the darkroom.
