摘要
现代军事雷达对抗中,快速准确获取辐射源方向角度信息至关重要,针对传统测向法精度较低的问题,本文提出长短基线相结合的方法建立测向算法模型,通过MATLAB对相位差进行测量求解,可以广泛应用于电子战情报处理领域。研究表明:与传统测向方法的精度相比,测向精度可达到1.2%。
In modern military radar confrontation, to obtain angular information of radiation sources quickly and ac-curately is very important. In order to overcome low measurement accuracy of conventional direction-finding meth-od, a direction measurement algorithm model combining short and long baseline is put forward, and phase differ-ence is measured and solved with MATLAB. This approach can be widely used in electronic warfare intelligence processing. Research showed that, comparing with traditional way, direction measurement accuracy of this method can be improved to 1 . 2%.
