Navigation System Failure Detection Based on FM Gauss Wavelet Transforms

Abstract

In order to solve the navigation system failure is difficult to detect small amplitude mutation problem, we proposed a model based on FM Gauss wavelet transform. The method uses the FM gauss wavelet transform values for real-time fault detection. It through simulation experiments completed analysis of the performance of the algorithm validation. The results show that the algorithm can effectively carry out fault diagnosis, it not only for large mutations detected fault but also has a good effect on the value of mutations fault and has slightly better detection results.
