Goal Orientation Algorithm Based On Three-axis Vibration Sensor And Hardware

This thesis mainly studied the arithmetic on vehicle bearing determination form a three-axis Seismometer using Rayleigh wave propagation. The moving target's three-dimension seismic signal could be collected by three-axis Seismometer, and then completed the feature extraction. Finally based on this arithmetic realizing the hardware of DSP micro system.By studying the seismic signal and reference of many literatures, using the method of time-frequency and power spectral analysis to extract feature. And find the ideal bearing arithmetic by analyzing extracted signals using correlation method. Considering signal's real-time process, we designed the high speed digital signal process (DSP) hardware system. Including signal pre-amplifying and conditioning circuit, A\D circuit and signal process circuit.This thesis's whole design is build on unattended ground sensor (UGS) system.
