研究了信息论准则的3种辐射声源数估计算法和盖氏圆辐射声源数估计算法,通过数值仿真对这4种算法的性能做出了对比分析,通过分析得知信息论方法适用于白噪声背景,盖氏圆方法不仅适用于白噪声背景也适用于有色噪声背景。
The three kinds of radiation source estimation algorithms and the cover sound emission source estimation algorithms are studied. The performance of these four algorithms is analyzed by numerical simulation. The results show that the information theory method is suitable for white noise Background, Gai circle method applies not only to white noise background but also to colored noise background.
