Interactions between radar and communications systems have been on our metaphorical radar for decades; however, the answer from the radar designers’ perspective has long been, just keep “them” out of our band. Increasingly, this perspective is not viable as both co mmunications and radar systems are searching for more spectrum. Furthermore, we may be missing potential performance advantages availed by joint operations. These advantages include both logistical benefits of RF system reuse, and some interesting system benefits by having access to more sophisticated RF topologies. In addition, because of the quickly falling costs of RF systems and a growing range of nontraditional applications, there is likely to be a significant growth in commercial interest in these joint systems. To access these advantages, we need a significant paradigm change in which we blur the line between communications and radar systems and start thinking of them as joint RF systems. These systems may be the first examples of truly cognitive RF networks
