This paper will introduce a cognitive radio testbed and associated technologies that have been developed by Northrop Grumman. The cognitive radio testbed is based on an internally developed hardware platform to create waveforms on demand over a broad spectral space. This advanced communication device employs a newly developed algorithm that exploits spectrum opportunities to create low-probability of interception and detection (LPI, LPD) waveforms. The testbed also integrates several proven and novel Northrop Grumman Technologies developed for signal intelligence (SIGINT) systems
