A Target Selection Algorithm of Seeker Based on the Prior Information and SVM

Abstract

Aiming at the phenomenon that the chaff and corner reflector released by surface ship can influence the selection of missile seeker, this paper proposed a multi-target selection method based on the prior information of false targets distribution and Support Vector Machine (SVM). By analyzing the false targets distribution law we obtain two classification principles, which are used to train the SVM studies the true and false target characteristics. The trained SVM is applied to the seeker in the target selection. This method has advantages of simple programming and high classification accuracy, and the simulation experiment in this paper confirms the correctness and effectiveness of this method.

An Analysis of Translation Strategies Used in External Publicity News from China Daily Based on Functional Equivalence Theory

“…A wide range of communication methods, including the Internet, film and television works, literary works, and more, and news reporting is also an important part of it such as external propaganda news. With new development challenges, foreign propaganda tries to start from the cultural environment of the target language to build a multidimensional ecological context that is consistent with the target language and make multidimensional adaptation and adaptability choices such as language level, communicative level, and cultural level, so that external propaganda news reports can be accurately conveyed and enjoyed by foreign audiences [1]. In this context, novel prerequisites emerge for external news dissemination in order to genuinely fulfill the objectives of publicizing information.…”

“…Its purpose is to report real events, and the language strives to be popular, true, lively, and interesting. When switching to external publicity, external publicity writers start from a cross-cultural perspective, adapt to the rich context conveyed by the news, and make dynamic choices and a series of adaptive activities from the multi-dimensional ecological context so that the news reports are both accurately conveyed and novel and concise, and better expand the dissemination coverage as well as publicity effect of the news [1].…”
