Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Commonly used inertial sensor signals are generally low-frequency or relatively stable signals, which can be sparsely represented under a specific basis, which provides the necessary conditions for the use of compressed sensing. For this reason, the present invention gives full play to the advantages of compressed sensing, and in order to further reduce the sampling number of signals, it proposes to combine random sampling and compressed sensing theory and apply it to inertial sensor dynamic signal processing, so that it can realize the original signal with less sampling data. At the same time, the accuracy of the output signal is improved, which provides an important reference for the use of inertial sensor signals in harsh environments.

Abstract

The invention discloses a real-time processing method for dynamic signals of inertial sensors. Firstly, the random sampling technology is used to fully reduce the sampling data of the signal; The algorithm completes the accurate reconstruction of the original signal to improve the output accuracy of the dynamic signal of the inertial sensor. Compared with the traditional method, the invention can effectively improve the precision of the output signal while greatly reducing the sampling data of the signal, so as to realize the real-time processing of the dynamic signal of the inertial sensor.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a method for real-time processing of dynamic signals of inertial sensors. Background technique [0002] With the development of science and technology, inertial navigation systems are widely used in related military and civilian fields. The system mainly measures the inertial attitude through inertial components, and then realizes navigation tasks. As one of the core components of the inertial navigation system, the inertial sensor is susceptible to external interference, which can easily cause navigation errors in an unstable environment. Therefore, the accuracy of the inertial sensor signal is a key factor restricting the performance of the inertial navigation system, especially Applied in the harsh environment where external unstable factors appear, the inertial sensor signal processing directly affects the accuracy and performance of the entire navigation system inf...
