Simulink Simulation of Direction-finding Algorithm of Phase Interferometer

相位干涉仪测向方法是一种重要的无线电测向方法,它不受信号幅度衰减的影响,只与电磁波到达不同天线阵元的时间有关,并且可以利用计算机快速计算。本文采用Simulink图形化编程语言,分别从时域和频域两个角度对相位干涉仪测向算法进行了计算机仿真,仿真结果表明该算法具有较高的测向精度。

Phase interferometer direction-finding is an important method in radio direction-finding.It only related to the time division of wave arrival between different antenna elements without be affected by the signal amplitude attenuation,and can be quickly calculated by computer.In this paper,the graphical programming language Simulink is adopted to simulate the direction-finding algorithm of phase interferometer respectively from the time domain and frequency domain.The simulation results show that the accuracy of the direction-finding algorithm is acceptable.
