A political and technical challenge for developing an operational ultrawideband (UWB) surveillance radar is the ability to comply with the many international regulations on the radio frequency (RF) spectrum. It is clear that the worldwide regulations on the RF spectrum have made it more difficult to get licenses for radar operation. More importantly, the recent auction of RF spectrum for civilian personal communications in several countries has reduced the traditional bands for radar spectrum access. This chapter will go over the beneficial uses of UWB surveillance radars, along with the attendant frequency allocation process. It is very difficult to get an RF allocation license for operating in any populated area. And the process is always changing, with the advent of personal communications, a widespread reliance on wideband communications, digital television and radio broadcast. A short history of the RF frequency allocation in recent time will show a summary of the process, and the story will present several lessons learned from obtaining licenses for UWB radars.
