在强载波干扰条件下，GPS、雷达等定位系统信号容易受到干扰，导致船舶定位精度下降，为此提出了强载波干扰条件下船舶组合定位信息融合方法。在强载波干扰条件下，通过周跳探测与修复算法，准确检测并修复GPS定位信息中的周跳，获取船舶GPS定位信息；利用空频联合斜投影算子滤波算法抑制干扰信息，获取船舶雷达定位信息；通过加权融合处理后的船舶GPS定位信息与船舶雷达定位信息，完成船舶组合定位信息融合。实验证明，该方法可以实现船舶组合定位信息有效融合，信息融合方差较小，证明该方法具备较高定位精度。
Under strong carrier interference conditions, GPS, Radar and other positioning system signals are prone to interference, leading to a decrease in ship positioning accuracy. Therefore, a method for combining ship positioning information fusion under strong carrier interference conditions is proposed. Under strong carrier interference conditions, using cycle slip detection and repair algorithms, accurately detect and repair cycle slips in GPS positioning information, and obtain ship GPS positioning information; Using the spatial frequency joint oblique projection operator filtering algorithm to suppress interference information and obtain ship radar positioning information; Through weighted fusion processing of ship GPS positioning information and ship radar positioning information, the fusion of ship combined positioning information is completed. Experimental results have shown that this method can effectively fuse ship combination positioning information, with a small variance in information fusion, demonstrating that this method has high positioning accuracy.
