The present disclosure discloses a real-time cleaning method for maritime non-combat targets and a system therefor, comprising: processing the historical track data in the historical database, mining the behavior rules of historical target tracks, screening out fixed targets (such as islands and floating objects) and regularly sailing targets (comprising regularly sailing military ships and civilian ships) in the target sea area, and classifying and storing the targets; detecting the similarity and repeatability between the track data points of historical non-combat targets (comprising fixed targets and regularly sailing civilian ships) which have little influence on battlefield situation analysis and the updated real-time target track data points in the current maritime battlefield environment, wherein if the real-time target track is similar and repeated to the historical non-combat target track, the real-time target is a non-combat target. With the method, the present disclosure can detect the maritime non-combat target in real time and accurately. DRAWING FIG. 1 acquiring a historical target track data set, wherein the historical target track data comprises a plurality of records, each record comprises a plurality of sub-records, and each sub-record comprises a plurality of features, wherein the features of each sub-record comprise time, position, speed, heading, friend or foe attribute and type 102 calculating a first multi-dimension record matching similarity between any two records based on the plurality of features of each sub-record merging the plurality of records according to the first multi dimension record matching similarity, and screening out fixed and regularly sailing target data sets and irregularly sailing target data sets in the historical target track data 104 cleaning the fixed and regularly sailing target data sets by using a cyclic threshold method according to a distance threshold and a proportional threshold, so as to obtain a fixed target data set, a regularly sailing military target data set and a regularly sailing civilian target data set 105 constructing a non-combat target data set based on the fixed target data set and the regularly sailing civilian target data set 106 acquiring a real-time target track data set calculating a second multi-dimension record similarity between each target track in the real-time target track data set and each non-combat target track in the non-combat target data set judging whether each target track in the real-time target track data set is a non-combat target track according to the second multi-dimension record similarity
