| 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 |
| Keywords: | direction of arrival space spectrum estimation ESPRIT algorithm complex electromagnetic environment |
