Due to the restriction characteristics of maritime target movement and formation, point sets matching between the bound formation and the detected one by terminal guidance has become an effective approach in selecting the predetermined target.. But the jamming existing within formation can cause the formation structure to change partially, which results in deterioration of the target selection performance. Based on the target selection need for anti-ship missile, the factors causing the position point sets to be differently distorted are analyzed, which mainly contain the navigation and detection errors of sensor, the bound information error, the formation targets motion and the released jamming. Subsequently, through effectively using the uncontaminated structure information, a predetermined target selection method for maritime formation that integrates geometric hashing and structure weighted mean Hausdorff distance was presented. Theoretical analyses and experimental results show that the method is not affected by the sensor navigation error and formations unitary movement; moreover, this method can effectively improve the target selection capability when there exist dilute jammings.
