船舶电容式导航传感器高频信号盲处理方法分析

Blind signal processing method for high frequency signal of ship capacitive navigation sensor

传统高频信号盲处理方法不能有效描述船舶传感器快速不动点的变化趋势。为解决上述问题,提出一种船舶电容式导航传感器高频信号盲处理分析方法。通过单位传感控制因数确定、电容导航频率确定2个步骤,完成船舶电容式导航传感器高频信号的获取。在此基础上,通过盲处理度量参数确定、处理判决阈值选取、高频信号盲分离3个步骤,实现新型分析方法的搭建。模拟对比试验结果显示,与传统方法相比,应用船舶电容式导航传感器高频信号盲处理分析方法后,快速不动点在时间、距离两方面的变化趋势,呈现明显的规律状态。

The traditional high-frequency signal blind processing method can not effectively describe the trend of fast fixed point of ship sensor. To solve the above problems, a blind signal processing method for high frequency signal of capacitive navigation sensor is presented. Through the two steps of unit sensor control factor determination and capacitance navigation frequency determination, the high frequency signal acquisition of ship capacitive navigation sensor is completed. On this basis, the new analysis method is built by three steps: the blind processing parameter determination, the decision threshold selection and the high frequency signal blind separation. The simulation results show that, compared with the traditional method, after the application of the high frequency signal blind processing analysis method of the ship capacitive navigation sensor, the fast fixed point in the two aspects of time and distance change trend, showing obvious regular state.
