Abstract: In allusion to the question that electromagnetic environment has become more and more complicated, the related technologies of the spectrum of existing monitoring systems was in depth studied, and its own characteristics was analyzed, and on this basis, the reasons of using a distributed spectrum monitoring system was discussed. Secondly, for the demand of the issue, this paper put forward a design concept of distributed spectrum monitoring system which is based on middleware, using the middleware to achieve the distribution of tasks and transmission of the results when coping with multiple testing tasks. Finally, designed and implemented the middleware, and the reliability and perform- ancc of middlcwarc were tested.
