摘　　要：船用导航传感器干扰信号处理一直都是船舶通信领域的热点问题,当前干扰信号抑制方法由于滤波环节较为落后,导致处理后信号误码率较高,设计双边滤波技术的船用导航传感器干扰信号抑制方法。构建船用导航传感器信号模型,计算信号噪声比、干扰噪声比。使用双边滤波技术对采集到的干扰信号进行滤波处理,并使用BOC原理对其展开调制。构建仿真实验环节对此方法使用效果展开分析,实验结果表明,此方法可有效控制信号误码率,提升导航信号可靠性。The interference signal processing of marine navigation sensor has always been a hot issue in the field of ship communication.The current interference signal suppression method is relatively backward due to the filtering link,which leads to a high bit error rate of the processed signal.This paper designs a bilateral filtering technology to suppress the interference signal of marine navigation sensor.The signal-to-noise ratio(SNR)and interference to noise ratio(LNR)of navigation sensors are calculated.The bilateral filtering technology is used to filter the collected interference signal,and BOC principle is used to modulate it.The experimental results show that this method can effectively control the bit error rate and improve the reliability of navigation signal.
