Fundamentally, this book seeks to capture the salient aspects of the exceedingly complex topic of radar and communication spectrum sharing, which is itself a menagerie of different problem spaces that depend on the particular goals one is attempting to achieve. The most prominent problem, and consequently the one most often first considered, is that of sharing between commercial communications and monolithic, stationary radars (e.g. for weather monitoring or air traffic control). Due to the sheer breadth of this topic, we do not attempt to codify all the many ways in which spectrum sharing could be performed. In fact, with the notion of radar spectrum sharing only rather recently becoming manifest due to the confluence of exponentially growing spectrum demand and emerging software-driven radio capabilities, one could well contend that we are now only glimpsing what will later be considered the earliest stages of spectrum sharing innovations.
