Testing for Coexistence in Crowded and Contested RF Environments

This paper discusses some of the key Research, Development, Test & Evaluation (RDT&E) challenges when developing and deploying RADAR & EW systems that need to function in congested and/or contested RF environments. Topics include an overview of the issues facing coexistence, such as a contested and congested spectrum, spectral sensing and sharing and dynamic spectrum allocation. This paper concludes with an overview of the characteristics and architectures of test systems that are used to create realistic RF environments to test systems under real-world operational conditions in a controlled laboratory environment.
