摘要
根据软件滤波的特点,设计了主机检测系统中的滤波流程,对周期性载波、脉冲信号干扰以及白噪声的滤除算法进行了分析研究。利用本文的方案,能对随机干扰信号的剔出起到良好的效果,以达到检测精度的提高,以保证船舶的安全航行。
According to the characteristic of software filter. The filter flow of main engine examination system was designed to study on the periodic carrier, the signal impulse disturbance as well as the white noise filtering algorithm. With the way proposed, good effect can be gotten on picking out random disturbance signal in order to achieve the enhancement of examination precision to guarantee safe navigation of ship.
