Today, the Multiple Hypothesis Testing (MHT) is generally accepted as the preferred approach for MTT systems, as it demonstrates better results in more complicated and uncertain environments. However, embedding such a mechanism to a deployed GNN-based system requires an extensive software change, and may introduce a major engineering risk to the working environment. Moreover, in a system that is deployed at different sites, which addresses operational environments of different complexities, such a change may be too costly and even superfluous. In this paper we will present a method which will address the challenge of multiple targets tracking in changing environments through a First Order Multiple Hypothesis Testing for a Global Nearest Neighbor engine. We will start with presenting the basics of multiple targets tracking, followed by a review of the proposed solution and conclude with simulations to verify its performance in different scenarios.enText/Conference Paper1617-5468
