The radio frequency spectrum has become very crowded with the increased use of commercial and personal communications devices. The worldwide spectrum committees require extreme measures to insure frequency avoidance by radar systems, to insure communications are maintained for emergency systems and flight safety. Radars operating in the frequency bands below 2 GHz have limited spectrum allocation,...
The radio frequency spectrum has become very crowded with a combination of commercial and personal communications devices. At the same time, the world-wide spectrum committees require extreme measures to insure frequency avoidance; such that communications are maintained, especially for emergency and flight safety. The radar community needs to adopt the techniques developed for cognitive communications...
Radar systems demand more spectrum to enable improved resolution of targets or for obstacle detection and tracking. The proliferation of WiFi communications has resulted in the “selling off” of many radio frequency bands, previously allocated to radar. A review of the IEEE Ultra wideband Standard and the process for obtaining frequency allocation points to significant challenges in future system acceptance...
