N2 - In order to estimate the state of uncertain models, a robust filter based on risk sensitive estimator is proposed, which could automatically change the state noise covariance according to the magnitude of the risk function. As a result, sample impoverishment could be mitigated. Another contribution of this paper is to take every sensor measurement into account, when large sample sets are needed to represent the system's uncertainty, thereby avoiding the risk of losing valuable sensor information during the update of the filter. A simulation example of submarine bearing and frequency tracking is presented, the experiment results show that new algorithm performs better than generic particle filter and unscented particle filter.
