An Algorithm of Segmentation Positioning Analysis Based on CSS

摘要

Wireless positioning technology is used to get the target position by sending a certain frequency signal in a certain space, then collect, detect, analyze the difference of feedback signal and signal sent. In order to reduce the chance of the collision of the signal in the air, the positioning algorithm is implemented by the segmentation positioning method. The key technology of segmented positioning lies in accurate ranging. Due to the complex and changeable working environment, there are large errors in the single time domain reflection method. In order to overcome this disadvantage, a comprehensive ranging analysis method is proposed in this thesis, i.e. the frequency-domain reflection and time-domain reflection integrated ranging is used to precisely separate the resistor part and capacitance part in the feedback waveform, and the feedback waveform is analyzed by wavelet transform to achieve the accurate positioning.
