应用高阶累积量辨识ＦＩＲ系统的方法已在众多领域得到广泛的应用研究．本文提出了一种估计地震于波方法－高阶累积量矩阵方程法．该方法在反射系数序列为非高斯、统计独立的随机过程假设条件下．适用于任意相让子波和任意加性高斯色噪声的情况，且运算时间较短，精度较为理想．模型和实际数据实验表明，该方法对于地震资料处理中的子波估计具有较好的应用前景． The application of high order cumulants to identify FIR system has been widely applied in many fields. In this paper, we propose a seismic wave-method-high-order cumulant matrix equation method. This method is based on the assumption that the reflection coefficient sequence is non-Gaussian and statistically independent. It is suitable for any phase let wavelet and any additive Gaussian color noises, and the operation time is short and the accuracy is better. The experimental results show that this method has a good application prospect for wavelet estimation in seismic data processing.
