Traditional detection probability evaluation method for infrared point target is not appropriate in the condition of complicated background due to the influence of background radiance. Firstly, this paper deduces the traditional detection probability evaluation method for point target under unitary background and analyzes its defects. Then, this paper introduces the idea of probability distribution into the traditional method and proposes a novel detection probability evaluation method under complicated backgrounds. Finally, a detection probability calculation instance shows that the new method can accurately estimate the detection probability under complicated backgrounds.
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.
