用MATLAB实现FFT的快速测向

Simulate the FFT's Fast Direction Finding with MATLAB

测向是一门实用技术,广泛应用于无线电管理、军事侦察、救援搜索等方面。FFT快速测向的原理就是利用FFT测向方法在阵元间进行相位角计算。利用MATLAB进行仿真可以更加直观地解释FFT快速测向的过程与原理。其仿真结果与理论分析是一致的,证明仿真程序是有效的。

Direction finding as a applied technology is widely used in the wireless management, military spy, succor and so on. The principle of FFT fast direction finding is to calculate phase angle between array elements by FFT direction finding method. The use of MATLAB simulation can be more intuitive to explain the process and principle of FFT fast direction finding. The simulation results are consistent with the theoretical analysis, and the simulation program is proved to be effective.
