Cognitive Radio (CR) has been proposed to address the spectrum congestion in communications. The spectrum congestion problem also affects other RF application such as Radar, Navigation and Electronic Warfare (EW). Recently, the concept of cognitive radio has been adopted by different communities dealing with RF signals: CR and DSA in communication, cognitive Radar/DSA Radar for radar application, cognitive GPS in Navigation and cognitive EW, to name a few. However, current research and development in these areas has been done separately, and functions of different RF applications reside on separated devices. To achieve the best spectrum efficiency, these research areas need to be integrated together to create a universal Cognitive RF platform. We will present our recent work and view on such a universal Cognitive RF platform and how to integrate spectrum sensing, RF signal detection/classification, RF signal parameter estimation, RF watermarking, frequency agile waveform generation technologies together to achieve ultimate spectrum efficient cognitive RF system. We will also present software defined radio implementation of some of the proposed technologies. Part of the SDR implementation was demoed at Globecom 2010 and received the Best Demo Award. This tutorial was given at the Electronic Warfare Summit, the IEEE Waveform Diversity and Design Conference, and the IEEE Milcom.
