复杂电磁环境下ESPRIT算法的测向性能

Performance of ESPRIT Algorithm in the Complex Electromagnetic Environment

摘要:

从复杂电磁环境的实际应用出发,从入射角度、阵元间距、信号带宽、多信源(邻近信号)这4个因素对旋转不变子空间算法的测向精度作了仿真研究,得出了一些结论,发现旋转不变子空间算法比多重信号分类算法更适合于在复杂电磁环境中的应用。

Abstract:

Since the electromagnetic environment has been becoming more and more complex, some new demands have been put forward to improve the application of space spectrum estimation. Aiming at the actual problems, such factors were studied as the incidence angle, the array elements spacing, noisy wide-band signals, and multiple signals (adjacent signal) by simulation. Some conclusions have been drawn, for example, ESPRIT algorithm is more suitable for the application in the complex electromagnetic environment than MUSIC algorithm
