An evaluation scheme of skywave radar coverage of ship target is researched. On the basis of fifteen kinds of indexes of the skywave radar coverage, a sort of model of coverage quantitative evaluation with three levels of hiberarchy is established by means of the modified analytical hierarchy process (AHP) based on grey relational grade (GRG), the quantitative calculation method of all level indexes is discussed, and the effectiveness ofthe model is verified. This method solve the problem in AHP effectively. The result shows that the evaluation scheme of skywave radar coverage is feasibility.
The principle of imaging method based on matched filtering and chaos theory are introduced. On this basis, a new method of range imaging using the correlation function of the chaotic signal is provided. At the same time, simulation models and simulation results are given. The experiment results show this method has the advantages of good range resolution and excellent anti-interference performance, the quality of the reconstruction image is fine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
