摘　　要：给出了一种基于广义均方误差的定量描述非线性滤波问题的非线性强度指标。利用该指标亦可评判非线性滤波算法的估计性能,从而可方便地选择合适的滤波算法。通过两个模拟算例验证了该判定准则的合理性和可行性。Measuring the degree of nonlinearity of the nonlinear filtering problems was discussed, a quantitative criterion for measuring the degree of nonlinearity of the nonlinear filtering problems, based on the concept of the generalized mean square error, was given in this paper. Simultaneously, it could tell about the estimation performance of the nonlinear filters. Simulated experiments showed that the criterion introduced here was feasible.
