基于电容式传感器空间滤波效应测速原理分析
摘要
Abstract
The basic principle of solids velocity measurement based on spatial filtering effect of capacitive sensor is presented.The theoretical response of capacitive sensor electrodes to permittivity impulse signals is derived
The relationship between the frequency bandwidth of capacitive sensor and solids velocity has been found. At last the method is discussed.
